A 5.00 kg carrying a charge of Q=60 uC is connected to a spring for which k=100N/m. The block lies on a frictionless horizontal track and the system is immersed in a uniform electric field of E=5.0e5 V/m. If the block is released from rest when the spring is unstretched.

A) By what maximum amount does the spring expand?

B) What is the equilibrium position of the block?

C) if the block is relesed from rest at x=0, how fast is it moving at x=0.25m?

D) now if instead of being released from rest the block is shoved to the left so that it starts with a velocity to the left of 2 m/s, what maximum distance to the left of x=0 would the block reach?

E) what maximum distance to the right of x=0 would the block reach?

F) where would the new equilibrium location be?

G) what if the block was shoved to the right giving it an initial velocity of 2 m/s. What maximum distance to the right of x=0 would the block reach?
