NOTE: use g=10.0m/s in your calculations 1. (15P) Uniform electric field with magnitude E is applied on a particle of mass m with positive charge q which is tied to the ceiling by a light string. If the system is in equilibrium, (a) Draw a free body diagram for the particle. (b) Obtain an expression for the angle 0 between the string and vertical direction as a function of m, q, and E. (c) Calculate 0 if E = 10*N/C, m = 3g, q = 4µC E %3D DALL
