  • Question 1/10
    4 / -1
    Acceleration due to gravity \'g\' for a body of mass \'m\' on earth\'s surface is proportional to (Radius of earth = R, mass of earth = M)
  • Question 2/10
    4 / -1
    A spring balance is graduated on sea level. If a body is weighed with this balance at consecutively increasing heights from earth\'s surface, the weight indicated by the balance
  • Question 3/10
    4 / -1
    The moon\'s radius is 1/4 that of the earth and its mass is 1/80 times that of the earth. If g represents the acceleration due to gravity on the surface of the earth, that on the surface of the moon is
    Solutions

  • Question 4/10
    4 / -1
    R is the radius of the earth and ω is its angular velocity and gp is value of g at the poles . The effective value of g at the latitude λ = 60o will be equal to
    Solutions

  • Question 5/10
    4 / -1
    At what height over the earth\'s pole, the free fall acceleration decreases by one percent (assume the radius of earth to be 6400 km)
    Solutions

  • Question 6/10
    4 / -1
    The diameters of two planets are in the ratio 4 : 1 and their mean densities in the ratio 1:2. The acceleration due to gravity on the planets will be in ratio
  • Question 7/10
    4 / -1
    At the surface of a certain planet, acceleration due to gravity is one-quarter of that on earth. If a brass ball is transported to this planet, then which one of the following statements is not correct
  • Question 8/10
    4 / -1
    Mass of moon is 7.34 × 1022 kg . If the acceleration due to gravity on the moon is 1.4 m/s2, the radius of the moon is
    (G = 6.667 × 10-11 Nm2 / kg2)
    Solutions

  • Question 9/10
    4 / -1
    What should be the velocity of earth due to rotation about its own axis so that the weight at equator become 3/5 of initial value? Radius of earth on equator is 6400 km.
    Solutions

  • Question 10/10
    4 / -1
