Question

help me out with this​

Answer 1

Answer:

the answer will be option b

Explanation:

the shortest distance covered by an particle will be your displacement (straight line) so 2r

and the distance will be circumference 2πr/2 (divided by 2 because semi circle) hence displacement=2r, distance π r

Answer 2

Answer:

displacement = 2R

distance = pi R

Explanation:

distance= this is the length of path travelled during the motion

distance = pi R

displacement = it is a vector which started from starting point of motion and headed towards end point of motion

displacement = 2R
