Question

If a cycle wheel of radius 4 $m$ completes one revolution in two seconds. Then acceleration of a point on the cycle wheel will be

$π^{2} m / s^{2}$
$2 π^{2} m / s^{2}$
$4 π^{2} m / s^{2}$
$8 π m / s^{2}$

The correct answer is: $4 pi to the power of 2 end exponent m divided by s to the power of 2 end exponent$

Centripetal acceleration $equals 4 pi to the power of 2 end exponent n to the power of 2 end exponent r equals 4 pi to the power of 2 end exponent open parentheses fraction numerator 1 over denominator 2 end fraction close parentheses to the power of 2 end exponent cross times 4 equals 4 pi to the power of 2 end exponent$
