Thanks a lot for all your help.

so then would it be ep=deltaE 1/2kx^2=fd and solve for x?

Well, I'm out of ideas for a) then.

ok so here's what I think may be right. a) ep=1/2*kd for a spring and Ep=EQ for the block so ep=ep+ek 1/2ks=EQ/d+0 d^3=2EQ/k b)if it is force that I use then F=EQ EK=kx x=EQ/k c) I understand now it is simple harmonic because no energy is lost right? d)same as a but minus...

No we haven't, I have never done a question like this before, and it feels like I'm walking in the dark hoping to stumble on to something.

A block having mass m and and a charge +Q is connected to a spring having a constant k. The block lies on frictionless horizontal track, and the system is immersed in a uniform electric field of magnitude E, directed east. If the block is released from rest when the spring is unstretched ( at...
