The moment of inertia of a disc of radius \( 0.5 \mathrm{~m} \) about its geometric axis is \( 2 \mathrm{~kg}-\mathrm{m}^{2} \). If a string is tied to its circumference and a force of 10 Newton is applied, the value of torque with respect to this axis will be :-
- (1) \( 2.5 \mathrm{~N}-\mathrm{m} \)
(2) \( 5 \mathrm{~N}-\mathrm{m} \)
- (3) \( 10 \mathrm{~N}-\mathrm{m} \)
(4) \( 20 \mathrm{~N}-\mathrm{m} \)
