  • Question 1
    4 / -1
    Assertion Smaller the orbit of the planet around the sun, shorter is the time it takes to complete one revolution.
    Reason According to Kepler\'s third law of planetary motion, square of time period is proportional to cube of mean distance from sun.
  • Question 2
    4 / -1
    Assertion Gravitational force between two particles is negligibly small compared to the electrical force.
    Reason The electrical force is experienced by charged particles only.
  • Question 3
    4 / -1
    Assertion There is no effect of rotation of earth on acceleration due to gravity at poles.
    Reason Rotation of earth is about polar axis.
  • Question 4
    4 / -1
    Assertion We can not move even a finger without disturbing all the stars.
    Reason Every body in this universe attracts every other body with a force which is inversely proportional to the square of distance between them.
  • Question 5
    4 / -1
    Assertion If a pendulum is suspended in a lift and lift is falling freely, then its time period becomes infinite.
    Reason Free falling body has acceleration equal to acceleration due to gravity.
  • Question 6
    4 / -1
    Assertion If earth suddenly stops rotating about its axis, then the value of acceleration due to gravity will become same at all the places.
    Reason The value of acceleration due to gravity is independent of rotation of earth
  • Question 7
    4 / -1
    Assertion The difference in the value of acceleration due to gravity at pole and equator is proportional to square of angular velocity of earth.
    Reason The value of acceleration due to gravity is minimum at the equator and maximum at the pole.
  • Question 8
    4 / -1
    Assertion For the planets orbiting around the sun, angular speed, linear speed, K.E. changes with time, but angular momentum remains constant.
    Reason No torque is acting on the rotating planet. So its angular momentum is constant.
  • Question 9
    4 / -1
    Assertion A force act upon the earth revolving in a circular orbit about the sun. Hence work should be done on the earth.
    Reason The necessary centripetal force for circular motion of earth comes from the gravitational force between earth and sun.
  • Question 10
    4 / -1
    Assertion The speed of revolution of an artificial satellite revolving very near the earth is 8 luns–1.
    Reason Orbital velocity of a satellite, become independent of height of satellite.
