Question

A particle is moving in a vertical circle. The tensions in the string when passing through two positions at angles 30^o and 60^o from vertical (lowest position) are T₁ and T₂ respectively, Then

• A. $T_{1} = T_{2}$
• B. $T_{1} > T_{2}$
• C. $T_{1} < T_{2}$
• D. $T_{1} \geq T_{2}$

Answer 1

Answer: (B)

$T_{1} > T_{2}$

Answer 2

$T = mg\cos\theta + \frac{mv^{2}}{r}$

As $\theta$increases T decreases

So

$T_{1} > T_{2}$
