Question

A particle is performing a uniform circular motion along a circle of radius R. In half the period of revolution, its displacement and distance covered are respectively.

विकल्प

• 2R, 2πR

• R, πR

• `sqrt(2R)`, 2πR

• 2R, πR

Answer 1

2R, πR

Explanation:

For a particle, performing the uniform circular motion. In half revolution, i.e., from A to B,

Displacement = AB = Length of diameter = 2R

Disance = `"Circumference"/2 = piR`
