Charges and Their Interactions
A homogeneous ball with mass and total charge (uniformly distributed) is placed on a horizontal -plane. The ball starts rolling without slipping under the influence of a uniform electrostatic field with Find the acceleration in meters per second squared of the center of mass of the ball.
If a point charge with mass is put at point which is at a distance of above the midpoint between two equal charges at a distance of apart, the point charge will be move to point If the speed of the point charge at point can be expressed as where and are coprime positive integers, what is the value of
Let and the permitivity of free space
There is a point charge with mass and charge on a uniformly charged sphere with charge and radius . As shown in the above diagram, there is a hole on the sphere, so the point charge can move into the hole. If the period of the point charge can be expressed as where and are coprime positive integers, what is the value of
Let and the permitivity of free space
