MCAT Physics Questions

Two objects, whose charges are +3 nC and -2 nC, are separated by 1.0 mm. Find the magnitude of the attractive force that either charge exerts on the other.

In the figure below, L = 1.0 mm, q$_1$ = +3 nC, q$_2$ = -2 nC, and q$_3$ is +4 nC. Find the magnitude and direction of the net electrostatic force on q$_3$

Two charged plates are set up as pictured below. A charged ball of mass m and charge q is to be thrown between the plates with initial velocity V$_0$. The ball is a vertical distance, d, from either of the plates. Find how far down range the ball travels.

A charged ball of mass m and charge Q is hung from a mass less pendulum. A uniform electric field along the horizontal causes the pendulum to swing up an angle $\theta$. Find the magnitude of the electric field.
