The centripetal acceleration of a particle in uniform circular motion is 18 ~ms ⁻² . If the radius of the circular path is 50 cm , the change in velocity of the particle in a time of 18 ~s is
Options
- A9 ~ms ⁻¹
- B2 ~ms ⁻¹
- C3 ~ms ⁻¹
- D6 ~ms ⁻¹
Correct answer
C. 3 ~ms ⁻¹
Step-by-step solution
In circular motion, aligned & a_c= v^2 r & v= a_c r = 18 50 10⁻² =3 ~m / s aligned Also, w= v r = 3 50 10⁻² =6 rad / s aligned & = t=6 18 = 3 & v=2 v 2 =2 3 6 =2 3 1 2 =3 ~m / s aligned
