Two equal forces act on two different objects, one of which has a mass ten times as large as the other. The larger object will have acceleration that the less massive object.

The larger object will have smaller  acceleration that the less massive object.

Explanation:

Generally force is mathematically represented as

=>  

at constant  force  we have

So if  m is  increasing a will be decreasing which means the object with the larger mass will have less acceleration

double the distance = divide strength by 4
