A car of mass 1 kg moves around a curve whose radius of curvature is 100 m at a speed of 10ms-1. What is the centripetal force on the car?
Correct answer: B. 1 N
- A. 10 N
- B. 1 N
- C. 100 N
- D. 0.1 N
Explanation
The centripetal force on an object moving in a circular path is given by the formula Fc = mv^2/r, where m is the mass of the object, v is the speed, and r is the radius of curvature. In this case, the mass of the car is 1 kg, the speed is 10 m/s, and the radius of curvature is 100 m. Plugging these values into the formula, we get Fc = (1 kg)(10 m/s)^2 / 100 m = 1 N. Therefore, the correct answer is Option B. Option A, C, and D are incorrect because they do not correctly apply the centripetal force formula to the given values.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
