Concept explainers

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…

Chapter 11, Problem 16PCE

The L-shaped object in Figure 11-41 consists of three masses connected by light rods. What torque must be applied to this object to give it an angular acceleration of 1.20 rad/s² if it is rotated about (a) the x axis, (b) the y axis, or (c) the z axis (which is through the origin and perpendicular to the page)?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

Four point charges of equal magnitude Q = 55 nC are placed on the corners of a rectangle of sides D1 = 27 cm and D2 = 11cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system where the positive y-direction is up and the positive x-direction is to the right. A. Which of the following represents a free-body diagram for the charge on the lower left hand corner of the rectangle? B. Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle.Numeric : A numeric value is expected and not an expression.Fx = __________________________________________NC.

Point charges q1=50.0μC and q2=-35μC are placed d1=1.0m apart, as shown. A. A third charge, q3=25μC, is positioned somewhere along the line that passes through the first two charges, and the net force on q3 is zero. Which statement best describes the position of this third charge?1) Charge q3 is to the right of charge q2. 2) Charge q3 is between charges q1 and q2. 3) Charge q3 is to the left of charge q1. B. What is the distance, in meters, between charges q1 and q3? (Your response to the previous step may be used to simplify your solution.)Give numeric value.d2 = __________________________________________mC. Select option that correctly describes the change in the net force on charge q3 if the magnitude of its charge is increased.1) The magnitude of the net force on charge q3 would still be zero. 2) The effect depends upon the numeric value of charge q3. 3) The net force on charge q3 would be towards q2. 4) The net force on charge q3 would be towards q1. D. Select option that…
