Question

A particle is moving in a circular
path of radius 10 m. The
displacement after half a circle
would be .... *​

Answer 1

Answer:

The answer will be 2r.

After the particle covers half path of the circle, the displacement can be easily calculated by measuring the distance between initial and final points. Displacement after half circle = AB=OA + OB Hence, the displacement after half circle is 2r.

Mark me brainliest

Answer 2

$\huge{\underline{\tt{\red{Answer-}}}}$

displacement- 20m

We all know that displacement is all about the total distance measured between initial and final points.

Displacement after half circle =>

=> AB=OA + OB

Hence, the displacement after half circle is $2\times10 = 20m$
