Question

a partical is moving in anti clock wise direction along a circle of radius R .calculate the distance and displacement covered by the partical (I) from A to C(ik) from A to D​

Answer 1

Explanation:

Given that,

Angle of A and B=60 degree

Now, distance of a particle between A and B

Distance travelled = length of arc AB

360×2πR

60

= πR

3

Hence, the distance covered by the objects is

3.

πR
