Question

A force of 100 N gives a mass m₁, an acceleration of 10 ms^–2 and of 20 ms^–2 to a mass m₂. What acceleration must be given to it if both the masses are tied together ?

Answer 1

Suppose, a = acceleration produced if m₁ and m₂ are tied together,

F = 100 N 

Let a₁ and a₂ be the acceleration produced in m₁ and m₂, respectively.

a₁ = 10 ms^–2, a₂ = 20 ms^–2 (given)
