The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Centripetal Force**: - Centripetal force is not a new type of force; rather, it is a term used to describe any real force that acts towards the center of a circular path, keeping an object in circular motion. 2. **Identifying Real Forces**: - The real forces that can act as centripetal forces include: - Gravitational force (e.g., Earth orbiting the Sun) - Frictional force (e.g., a car turning on a road) - Tension force (e.g., a ball on a string being swung in a circle) - Electrostatic force (e.g., electrons orbiting a nucleus) - Normal force (e.g., a ball rolling in a bowl) - Magnetic force (e.g., charged particles in a magnetic field) 3. **Centripetal Force Formula**: - The formula for centripetal force (\( F_c \)) is given by: \[ F_c = \frac{mv^2}{r} \] - Where \( m \) is the mass of the object, \( v \) is the velocity, and \( r \) is the radius of the circular path. 4. **Conclusion**: - The statement that "centripetal force is provided by real forces acting on the body in motion" is **true**. This is because any of the aforementioned real forces can serve as the centripetal force depending on the situation.

    When a cyclist turns on a circular path,the necessary centripetal force is provided by friction between the tyres and the road. If centripetal force is not provided by friction, then for the vehicle to move on circular path, the track is banked. If the speed of a vehicle is doubled, then for safety of vehicle

    Assertion : The forces acting on a body can be replaced by the resultant force only as regards the motion of the body as a whole. Reason : The resultant force can not replace the several forces acting on a body in other respects.

    If no force acts on a body, it will

    If no external force acts on a body, it will

    A body is said to be under balanced forces when the resultat force acting on the body is
