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

The force needed to accelerate an object is directly proportional to its mass (F = ma). Therefore, to provide equal acceleration to both blocks, the force applied to the 10-N block must be 10 times greater than the force applied to the 1-N block, according to Newton's second law.
