Question

A particle is moving in circular path of radius 'r'. The displacement after half a circle would be

a) zero

b) 3.14 r

c) 2 r

d) 2 x 3.14 x r​

Answer 1

Step-by-step explanation:

Correct option is

C 2 r

Displacement at half path is the shortest distance between the initial and final point.

So, it's equal to twice the radius of the circle =2r

Answer 2

Answer:

2r

Step-by-step explanation:

disp=smallest distance between starting point and ending point.
