4. Suppose a man places an insulating slab on the ground and puts a large aluminium sheet on top. Will he get an electric shock if he touches the aluminium sheet next morning? Support your answer with reason.

answer; equivalent to a one(1) horsepower motor;

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
