Question

A partice is moving in a vertical circle. The tension in the string when passing through two positions at angles ${30}^{\circ }$ and ${60}^{\circ }$ from downward vertical are $T_1$ and $T_2$ respectively. Then

• A. $T_1=T_2$
• B. $T_2>T_1$
• C. $T_1>T_2$
• D. Tension in the string always remains the same .

Answer 1

The correct option is C $T_1>T_2$

In vertical circular motion under gravity, tension is maximum at lowest position and decreases with upward circular motion.
$\Rightarrow T_1>T_2$
