A small block of massmand charge Q is placed on an insulated, frictionless, inclined plane of angle THETA
(a) Find an expression for the magnitude of the electric field that enables the block to remain at rest. (Use any variable or symbol stated above along with the following as necessary: g for the acceleration due gravity.)
E = ________
(b) If m = 5.16 g, Q = -6.79 µC, and THETA = 24.9 DEGREE, determine the magnitude and the direction of the electric field that enables the block to remain at rest on the incline.
|magnitude= _________|| |
as in the figure below. An electric field is applied parallel to the incline.
