1.Two metal balls are the same size
but one weighs twice as much as the other. The balls are dropped from the

takes the balls to reach the ground below will be:
 
(a)
| about half as long for the heavier
ball as for the lighter one.
|
(b)
| about half as long for the lighter
ball as for the heavier one.
|
(c)
| about the same for both balls.
|
(d)
| considerably less for the heavier
ball, but not necessarily half as long.
|
(e)
| considerably less for the lighter
ball, but not necessarily half as long.
