Question

If a force of $10N$ is applied on the $1kg$ block at $t=0$, find the tension $T_1$ at that instant. (Assume there is no friction between blocks and the ground).

• A. $10N$
• B. $\frac{70}{6}N$
• C. $\frac{50}{6}N$
• D. Zero

Answer 1

The correct option is D Zero

When $10N$ is applied on $1kg$ block, the string between $1kg$ and $2kg$ block becomes loose. Due to which, tension $T_1$ in the string will be zero.
