To make two bodies A and B experience an equal acceleration, forces 6 N and 4 N are applied, respectively. If the bodies are combined, then to produce the same acceleration, the force applied should be _______ N.

Answer

10

Explanation

F = ma. Here a is constant
`thereforeF_(1)=m_(1)aandF_(2)=m_(2)a`
`rArr6=m_(1)aand4=m_(2)a`
If .F. is force on `m_(1)+m_(2)`, then
`F=(m_(1)+m_(2))a=m_(1)a+m_(2)a`
6 + 4 = 10 N
Hence, the correct answer is 10.
