Question

A bog of mass $$ m = 50\ gm$$ is oscillating with the help of a string, the maximum value of angle from the vertical attained by the bog is $$60^{o}$$ .The tension in the string at extreme position is

A
0.25 N
B
1N
C
1.5 N
D
2N
Solution
Verified by Toppr

Correct option is A. 0.25 N
In the given problem at the extreme position, the tension in the string and the weight mg balance each other.
But weight mg is resolved into $$mgcos\theta$$ and hence
$$T = mgcos\theta = \left(50 \times 10^{-3}\right) \times (10) \times \frac{1}{2}=0.25 N$$
