A block with a mass of 10.2 g and a charge of +6.98 x 10'5 C is placed in an electric eld with x component EX = 4.41 X 103 N/C, y component Ev = -773 WC, and 2 component E2 = O. (a) What is the magnitude of the electrostatic force on the block and (b) what angle does that force make with the positive x direction? If the block is released from rest at the origin at time t = 0, what are its (c) x and (d) y coordinates at t = 2.50 s?
