A 70.0-g block carrying a charge Q = 39.0 µC is connected to aspring for which k = 77.0 N/m. The block lies on a frictionless,horizontal surface and is immersed in a uniform electric field ofmagnitude E = 4.68 104 N/C directed as shown in the figure below.The block is released from rest when the spring is unstretched (x =0).
(a) By what maximum distance does the block move from its initialposition?
________ cm
(b) Find the subsequent equilibrium position of the block and theamplitude of its motion.
possition ________ cm
amplitude ________ cm
(c) Using conservation of energy, find a symbolic relationshipgiving the potential difference between its initial position andthe point of maximum extension in terms of the spring constant k,the amplitude A, and the charge Q.
ÎV = _________
