Question

3. A particle moves in a circle of radius R from A to B as shown
in figure. The distance covered by the object is

Answer 1

Answer:

Given that,

Angle of A and B=600

Now, distance of a particle

between A and B

Distance travelled = length of arc AB

   =36060×2πR

  =3πR

Hence, 

the distance covered by the objects is 3πR
