Question

3.
A car moves with constant speed of
10 m/s in a circular path of radius
10 m. If the mass of the car is
1000 kg, then the centripetal force
for the car is ....
(1) 104 N
(2) 106N
(3) 105 N
(4) None​

Answer 1

Answer:

(D)NONE OF THESE

Explanation:

v=10m/s

R=10m

mass=1000kg

therefore

centripetal force =mv²/R

=1000×100/10

=10⁴N

therefore ,option (d)none of these
