You lift a 100 N boulder 1 m off the ground. How much work is done on the boulder? If it took 2 s, how much power was expended when you lifted the boulder? What is the
gravitational potential energy of the boulder at the 1 m position?

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
