Two particles A and B are moving in uniform circular motion in concentric circles of radii r_{A} and r_{B} with speed v_{A} and v_{B} respectively. Their time period of rotation is the same. The ratio of angular speed of A to that of B will be:

Solution & Step-by-step Explanation

The angular speed (ω) is related to the time period (T) by the formula: ω = \frac{2 π}{T} Since both particles have the same time period of rotation (T_{A} = T_{B}): ω_{A} = \frac{2 π}{T _{A}} and ω_{B} = \frac{2 π}{T _{B}} \frac{ω _{A}}{ω _{B}} = \frac{T _{B}}{T _{A}} = 1 The ratio is 1 : 1 .

Try it yourself before checking the explanation above.

Two particles A and B are moving in uniform circular motion in concentric circles of radii r_{A} and r_{B} with speed v_{A} and v_{B} respectively. Their time period of rotation is the same. The ratio of angular speed of A to that of B will be:

r_{A} : r_{B}

v_{A} : v_{B}

r_{B} : r_{A}

1 : 1
