Using the formula for torque τ =( textdifference in angular momentum/ texttime) τ =(4A-A/4)=(3A/4)

Q. A particle has angular momentum equal to A. The angular momentum becomes 4A after 4 sec. Find the torque applied:

$\frac{A}{4}$

$\frac{3 A}{4}$

4A

3A

Using the formula for torque $τ = \frac{difference in angular momentum}{time}$ $τ = \frac{4 A - A}{4} = \frac{3 A}{4}$

Q. A particle has angular momentum equal to A. The angular momentum becomes 4A after 4 sec. Find the torque applied:

4A​

43A​

4A

3A

Using the formula for torque τ=timedifference in angular momentum​ τ=44A−A​=43A​

$\frac{A}{4}$

$\frac{3 A}{4}$

Using the formula for torque $τ = \frac{difference in angular momentum}{time}$ $τ = \frac{4 A - A}{4} = \frac{3 A}{4}$
