Question

A block of mass $50$ kg is kept on another block of mass $1$ kg as shown in figure. A horizontal force of $10$ N is applied on the $1$ kg block. (All surface are smooth). Find $(g=10m/s^2)$ force exerted by B on A.

• A. $500$ N
• B. $510$ N
• C. $1000$ N
• D. $1020$ N

Answer 1

The correct option is A $500$ N

F.B.D.of 1 kg block:
