Question

An object is moving around circular path of radius 7km He covers 2 in a half Revolution. Find distance and displacement.​

Answer 1

Estimate the distance covered and displacement when the particle (i) covers half circular path and (ii) completes the total circular path once. = 2πr=2×227×7=44 cm. Hence displacement is 2×7 = 14 cm from A to B →(AB).

Answer 2

Explanation:

Estimate the distance covered and displacement when the particle

(i) covers half circular path and

(ii) completes the total circular path once. = 2πr=2×227×7=44 cm.

Hence distance covered =442=22 cm.
