Asked by anonymous
A sphere of unknown mass with a net charge, Q is released from rest in a uniform electric field, E. After it travels a distance,d , it acquires a kinetic energy, K . Find the magnitude of the electric field in terms of K,Q , and .d [Hint: remember the Work/Energy theorem]. The effects of work done by gravity are negligible.
I know the work energy theorem, but how does this relate to charge?
Thank you.

work done=force*d=Eqd
ke gained=work done
K=Eqd
E=K/qd
ke gained=work done
K=Eqd
E=K/qd
