(A) Given: Radius $r = 50\, cm$,Number of revolutions $N = 10$,Time $t = 20\, s$.Frequency $n = \frac{N}{t} = \frac{10}{20} = 0.5\, Hz = \frac{1}{2}\, Hz$.The centripetal acceleration $a$ is given by $a = \omega^2 r = (2\pi n)^2 r = 4\pi^2 n^2 r$.Substituting the values: $a = 4 \times (3.14)^2 \times (0.5)^2 \times 50$.$a = 4 \times 9.8596 \times 0.25 \times 50$.$a = 492.98\, cm/s^2 \approx 493\, cm/s^2$.

For a particle in a non-uniform accelerated circular motion:

Easy

View Solution

$A$ particle moves on a circle of radius $0.1 \ m$ with a velocity $v = 1.0t$. The total acceleration at $t = 5 \ s$ will be ........ $m/s^2$.

Medium

View Solution

$A$ particle of mass $m$ is moving in a circular path of constant radius $r$ such that its centripetal acceleration is varying with time as $a_c = k^2rt^2$. The power delivered to the particle by the forces acting on it is $(k = \text{constant})$
