An insulating sphere of mass m and positive charge q is attached to a spring with length h and spring constant k_s and is at equilibrium. An infinitely long wire with positive linear charge density lamda is placed a distance l away from the charged mass at equilibrium as shown below (note that the position of the top of the spring is fixed):The previous length of the spring was h . What is the new length of the spring in terms of h , q , K_e (type "ke"), lambda

h-(2*ke*q*lambda)/(ks*l)

Thank you very much
