Question

$1kg$ of block is tied to $1m$ rope of mass $5kg$ as shown. The tension at the midpoint of the rope is

• A. $60N$
• B. $30N$
• C. $10N$
• D. $35N$

Answer 1

The correct option is D $35N$

Tension at the mid - point of the rod = Weight of the rod below the mid-point

+ weight of the block

Weight of rod = $50$ N

Weight of block = $10$ N

Therefore , tension at mid-point of the rod = $(\frac{50}{2}+10)$ $N$

= $35$ $N$
