SECTION – B NUMERICAL PROBLEMS
1. Find the percentage decrease in weight of a body when taken to a height of 32km abovethe surface of earth , R = 6400 km.
2. At what height above the surface of the earth does the acceleration due to gravity reduce to 64 % of its value on the surface of the earth . R = 6400 km.
3. 15. How much below the surface of the earth does the acceleration due to gravity become1 % of its value at earth’s surface ?
4. 16. A body weighs 63 N on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth ?
5. Assuming the earth to be a sphere of uniform mass density, how much would a body weigh half way down to the centre of the earth if it weighed 250 N on the surface?
6. Find the potential energy of a system of four particles of equal masses M placed at the corners of a square of side L. Also obtain potential at the centre of the square.
7. A rocket is fired from the earth towards the sun. At what point on its path is the gravitational force on the rocket zero? Mass of sun = 2x 1030kg, mass of the earth = 6x1024kg. Neglect the effect of other planets etc. Orbital radius = 1.5x 1011m.
8. A Saturn year is 29.5 times the earth year. How far is the Saturn from the sun if the earth is 1.5 x 108km away from the sun?
9. The escape velocity of a projectile on earth’s surface is 11.2 kms-1. A body is projected out with thrice this speed. What is the speed of the body far away from the earth? Ignore the presence of the sun other planets.
