- Q1. According to Newton's Universal Law of Gravitation, the force of attraction between two point masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. What is the unit of the Universal Gravitational Constant (G)?
- Nm/kg
- Nm^2/kg^2
- Nkg/m^2
- Nkg^2/m^2
- Q2. The acceleration due to gravity (g) at a height 'h' above the Earth's surface decreases. If R is the radius of the Earth, for small values of 'h' compared to R, the approximate formula for g at height h is:
- g(1 - h/R)
- g(1 + h/R)
- g(1 - 2h/R)
- g(1 + 2h/R)
- Q3. Kepler's second law states that the line joining a planet to the sun sweeps out equal areas in equal intervals of ____.
- Q4. Which of the following statements is true about the gravitational force?
- It is always repulsive.
- It is a central force.
- It is a non-conservative force.
- It depends on the medium between the masses.
