Question
A small block of mass m and charge Q is placed on an insulated, frictionless, inclined plane of angle θ as shown. An electric field is applied parallel to the incline. (a) Find an expression for the magnitude of the electric field that enables the block to remain at rest. (b) If m = 5.40 g, Q = -7.00 μC, and θ = 25.0°, determine the magnitude and the direction of the electric field that enables the block to remain at rest on the incline.
