Suppose that the actual coefficent of friction is one and a half times as large as the value of . That is, .Under these circumstances, what is the magnitude of the force of friction that the floor applies to the ladder

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
