Question

Which of the following graphs correctly represents uniform angular retardation of a body?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Angular retardation $\left(\alpha \right)=-\frac{d\omega }{dt}$ (in ${\text{rad/s}}^2$)
For uniform angular retardation $\alpha =$ constant
Since the slope of $\omega$ vs time graph gives angular acceleration, the slope should be a negative constant to get uniform angular retardation.
$\therefore$ Option (c) is correct.
