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 x=0)
a)By what maximum does the spring expand
all i have is -kx1=Eq-kx2
x2=eq/k
b)What is the equilibrium position of the block?
in not sure of this isn't it the same as number one?
c) Show that the blocks motion is simple harmonic, and determine its period
I assume its just T=2pie*root m/k
d) What if? Repeat part (a) if the coefficient of kinetic friction between block and surface is Fu (u as in the coefficient of friction)
I don't want the answers I would love the tools to find them (though answers would be a bonus ) any help would be appreciated, thanks. oh and the spring is attached to the block
