A 10-N block and a 1-N block lie on a horizontal frictionless table.To push them with equal acceleration,we would have to push with
A)equal forces on each block.
B)10 times as much force on the heavier block.
C)10 squared or 100 times as much force on the heavier block.
D)one-tenth as much force on the heavier block.
E)none of the above
