0-g block carrying a charge Q= 35.0 micro-C is connected to a spring for which k=78.
A 74.0-g block carrying a charge Q= 35.0 micro-C is connected to a spring for which k=78.0N/m. The block lies on a frictionless, horizontal surface and is immersed in a uniform electric field of magnitutde E= 4.86*10^4 N/C. If the block is released what maximum distance does teh block move from its initial position? (b) find the susequent equilibrium position of the lobck and teh amplitude of its motion. (c) Using conservation of energy, find a symbolic relationship giving the potential difference between its initial position and the point of maximum extension in terms of the spring constant k, the amplitude A, and teh charge Q.
