Question

13. A particle moves along a semi-circle of radius R. It starts from A and moves in anticlockwise direction to B as shown
The displacement and distance travelled by the particle is
​

Answer 1

,

Angle of A and B=60

0

Now, distance of a particle between A and B

Distance travelled = length of arc AB

=

360

60

×2πR

=

3

πR

Hence, the distance covered by the objects is

3

πR
