A-3.0 nc charge is on the x-axis at x = -5.0 cm and a +4.0 nc charge is on the x-axis at x = 18 cm . at what point or points on the y-axis is the electric potential zero?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
