  1. Asked: October 28, 2020In: Class 9

    What happens to the force between two objects, if the masses of both objects are doubled?

    9 PhysicsMaster
    Added an answer on December 14, 2020 at 9:13 am

    F is directly proportional to the product of masses of the objects. If the masses of both the objects are doubled, then the gravitational force becomes four times the original value. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-10/

  2. Asked: October 28, 2020In: Class 9

    What happens to the force between two objects, if the distance between the objects is doubled and tripled?

    9 PhysicsMaster
    Added an answer on December 14, 2020 at 9:12 am

    F is inversely proportional to the square of the distances between the objects. If the distance is doubled, then the gravitational force becomes one-fourth of its original value. Similarly, if the distance is tripled, then the gravitational force becomes one-ninth of its original value. For more ansRead more

    F is directly proportional to the masses of the objects. If the mass of one object is doubled, then the gravitational force will also get doubled. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-10/

  4. Asked: October 28, 2020In: Class 9

    If the moon attracts the earth, why does the earth not move towards the moon?

    9 PhysicsMaster
    Added an answer on December 14, 2020 at 9:08 am

    The Earth and the moon experience equal gravitational forces from each other. However, the mass of the Earth is much larger than the mass of the moon. Hence, it accelerates at a rate lesser than the acceleration rate of the moon towards the Earth. For this reason, the Earth does not move towards theRead more

  5. Asked: October 28, 2020In: Class 9

    The earth and the moon are attracted to each other by gravitational force. Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth? Why?

    9 PhysicsMaster
    Added an answer on December 14, 2020 at 9:07 am

    According to the universal law of gravitation, two objects attract each other with equal force, but in opposite directions. The Earth attracts the moon with an equal force with which the moon attracts the earth. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9Read more
