The electric field between the plates of a parallel-plate capacitor is horizontal, uniform and has a magnitude E. A small object with a charge of -2.30 µC is attached to the string. Assume that the tension in the string is 0.350 N, and the angle it makes with the vertical is 11°.
(a) What is the mass of the object?
g
(b) What is the magnitude of the electric field?
N/C
