Question

Car on curved road necessary centripetal force is provided by

Answer 1

it is given by friction force

Answer 2

HELLO THERE!

When a car is moving along a curved road, then the centripetal force attracting it towards the centre will depend on the mass of the car, radius of curvature of the curve path, and the velocity with which the car is moving as:

$F_{c} = \frac{mv^{2}}{r}$

Where F is the centripetal force, v is the velocity of the car and r is the radius of curvature of the curved path.

Now, v = rω (where ω is the angular velocity).

Substituting v in the equation, we get:

$F_{c} = m\omega^{2}r$

REFER TO THE DIAGRAM.

Hope it helps :)
