Question

A hanging rope can withstand a tension of 750 N. The minimum acceleration for a man of 50 kg to climb up without breaking the rope is $(g=10\text{ ms}^{-2})$

• A. $6\text{ ms}^{-2}$
• B. $4\text{ ms}^{-2}$
• C. $5\text{ ms}^{-2}$
• D. $7\text{ ms}^{-2}$
• E. $2\text{ ms}^{-2}$

Hint:

Logic Tip: The question phrasing says "minimum acceleration... without breaking," but physically, $5\text{ ms}^{-2}$ is the \textit{maximum} acceleration the man can have before the rope snaps. Any acceleration greater than 5 will exceed 750 N.

Answer 1

The Correct Option is C
