An object of mass 2 kg moves with a velocity of 10 ms1 round at circle of radius 4 m. Calculate the centripetal force on the object
- 25 N
- 100 N
-
50 N
- 40 N
The correct answer is: C
Explanation
Centripetal force,F = \( \frac{mv^2}{r} \)
= \( \frac{2 \times 10^2}{4} \)
= \( \frac{200}{4} \)= 50N
