Question 178 of 183

If a body moving in a circular path maintains constant speed of 10ms−110m{s}^{-1} , then which of the following correctly describes the relation between acceleration and radius?

Show answer and solution

Answer: (D)


V = constant

⟹⟹ No tangential acceleration

⟹⟹ Only centripetal acceleration

a=v2Ra=\dfrac{{v}^{2}}{R}

⟹aR=constant⟹aR=constant

⟹a∝1R⟹a\propto \dfrac{1}{R}
