Assertion: Work done by the gravitational force through a certain distance is constant irrespective of the fact that the body has a uniform or accelerated motion.
Reason: Gravitational force is a conservative force.
Explanation:
- Work done by a force is given by the product of the force and the displacement of the object in the direction of the force.
- The formula for work done is given by W = F * d * cosθ, where W is the work done, F is the force, d is the displacement, and θ is the angle between the force and displacement vectors.
- In the case of gravitational force, the work done is given by W = m * g * h, where m is the mass of the object, g is the acceleration due to gravity, and h is the height or displacement in the vertical direction.
- The work done by the gravitational force is independent of the path taken by the object. It only depends on the initial and final positions of the object.
- This is because gravitational force is a conservative force, which means the work done by the force is path independent.
- The work done by a conservative force only depends on the initial and final positions of the object and not on the path taken.
- In the case of uniform motion, the work done by the gravitational force is constant as long as the object moves along a vertical line.
- In the case of accelerated motion, the work done by the gravitational force is also constant as long as the object moves along a vertical line.
- Therefore, the assertion is true. The work done by the gravitational force through a certain distance is constant irrespective of the fact that the body has a uniform or accelerated motion.
- The reason given is also true. Gravitational force is indeed a conservative force.
- However, the reason does not provide a correct explanation for the assertion. The reason talks about the path independence of the work done by a conservative force, but it does not directly explain why the work done by the gravitational force is constant in both uniform and accelerated motion.
- Therefore, the correct answer is option B. Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
