Question

can anyone please solve this...

Answer 1

F = mv²/r

[ Given, m = 500kg , r = 50m , v = 36kmph = 10m/s .]

Now,

Centripetal force = 500 ( 10)² / 50 = 10(10²) = 10³ kgm²/s² = 1000N .

The answer is Option ( A) , 1000N

Answer 2

Hi.

Here is your answer---

_________________

Given---

Mass of the Car(m) = 500 kg.

Radius of the Circular Paths(r) = 50 m.

Velocity of the Car(v) = 36 km/hr.
                                  = 36 × (5/18) m/s.   [Changing into m/s]
                                  = 2 × 5 m/s.
                                  = 10 m/s.

Using the Formula,

 Centripetal Force = mv²/r
                             = (5 × 10²)/50
                             = 5 × 2
                             = 10 N.

Thus, the Centripetal Force acting in the Circular Path is 10 N.
