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
A
25 N
B
100 N
C
50 N
D
40 N
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Centripetal force,
F = \( \frac{mv^2}{r} \)
= \( \frac{2 \times 10^2}{4} \)
= \( \frac{200}{4} \)= 50N
