Chapter 5, Problem 5.5OQ
An experiment is performed on a puck on a level air hockey table, where friction is negligible. A constant horizontal force is applied to the puck, and the pucks acceleration is measured. Now the same puck is transported far into outer space, where both friction and gravity are negligible. The same constant force is applied to the puck (through a spring scale that stretches the same amount), and the pucks acceleration (relative to the distant stars) is measured. What is the puck’s acceleration in outer space? (a) It is somewhat greater than its acceleration on the Earth. (b) It is the same as its acceleration on the Earth. (c) It is less than its acceleration on the Earth. (d) It is infinite because neither friction nor gravity constrains it. (e) It is very large because acceleration is inversely proportional to weight and the puck’s weight is very small but not zero.

- The magnitude of the force between a pair of point charges is proportional to the product of the magnitudes of their charges and inversely proportional to the square of their separation distance. Four distinct charge-pair arrangements are presented. All charges are multiples of a common positive charge, q. All charge separations are multiples of a common length, L. Rank the four arrangements from smallest to greatest magnitude of the electric force.arrow_forwardA number of electric charges has been placed at distinct points along a line with separations as indicated. Two charges share a common magnitude, q (lower case), and another charge has magnitude Q (upper case). The signs of the charges are indicated explicitly such that ∣∣+q∣∣∣∣+Q∣∣=∣∣−q∣∣==∣∣−Q∣∣=qQ Four different configurations of charges are shown. For each, express the net electric force on the charge with magnitude Q (upper case) as F⃗E=FE,xî where the positive x direction is towards the right. By repositioning the figures to the area on the right, rank the configurations from the most negative value to the most positive value of FE,x.arrow_forwardA collection of electric charges that share a common magnitude q (lower case) has been placed at the corners of a square, and an additional charge with magnitude Q (upper case) is located at the center of that square. The signs of the charges are indicated explicitly such that ∣∣+q∣∣∣∣+Q∣∣=∣∣−q∣∣==∣∣−Q∣∣=qQ Four unique setups of charges are displayed. By moving one of the direction drawings from near the bottom to the bucket beside each of the setups, indicate the direction of the net electric force on the charge with magnitude Q, located near the center, else indicate that the magnitude of the net electric force is zero, if appropriate.arrow_forward
- In Dark Souls 3 you can kill the Ancient Wyvern by dropping on its head from above it. Let’s say you jump off the ledge with an initial velocity of 3.86 mph and spend 1.72 s in the air before hitting the wyvern’s head. Assume the gravity is the same as that of Earth and upwards is the positive direction. Also, 1 mile = 1609 m. A) How high up is the the ledge you jumped from as measured from the wyvern’s head? B) What is your velocity when you hit the wyvern?arrow_forwardA conducting sphere is mounted on an insulating stand, and initially it is electrically neutral. A student wishes to induce a charge distribution similar to what is shown here. The student may connect the sphere to ground or leave it electrically isolated. The student may also place a charged insulated rod near to the sphere without touching it. Q. The diagrams below indicate different choices for whether or not to include a ground connection as well as the sign of the charge on and the placement of an insulating rod. Choose a diagram that would produce the desired charge distribution.

The person is holding the pan a distance y0 = 1.10 m above the ground when they launch the pancake. The pancake just barely touches the ceiling, which is at a height y = 2.47 m above the ground. A) What must be the initial velocity of the pancake to reach that height? B) This person, shocked that they almost hit the ceiling, does not catch it on the way down and the pancake hits the floor. Assuming up as the positive direction, what is the velocity of the pancake when it hits the floor, ruining breakfast and this person’s day?arrow_forward
