A 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.
A 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.
For each part make sure to include sign to represent direction, with up being positive and down being negative.

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?

- A 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.
