Question

A particle moves with a uniform speed of 5 m/s in a circular path. If the speed increases to 8 m/s in the 20th second. The motion of the particle in the 22nd second will be

• A. Uniform circular motion
• B. Non uniform circular motion
• C. Linear motion, since the particle flies off from the circular path
• D. Non linear motion, since velocity has increased

Answer 1

The correct option is A Uniform circular motion

The speed of the particle is not increasing gradually with time, but it increased only at 20th second. The speed of the particle will again be a constant from 21st second onwards and hence it represents uniform circular motion
