A horizontal force 10 N is applied to a block AA as shown in figure. The mass of blocks AA and BB are 2 kg and 3 kg respectively. The blocks slide over a frictionless surface. The force exerted by block AA on block BB is : A horizontal force 10 N is applied to a block A as shown in figure. The mass of blocks A and B are 2 kg and 3 kg

Options

  1. A4N
  2. B6N
  3. C10N
  4. DZero

Correct answer

B. 6N

Step-by-step solution

F=(M1+M2)aa=102+3=2 ms−2F′=M2(2)=3×2 N=6 N\begin{aligned} & F=\left(M_1+M_2\right) a \\ & a=\frac{10}{2+3}=2 \mathrm{~ms}^{-2} \\ & F^{\prime}=M_2(2)=3 \times 2 \mathrm{~N}=6 \mathrm{~N}\end{aligned}
