All the Best! 1 / 10 The upward force exerted by a fluid on an immersed body is called Gravity Magnetic force Friction Buoyant force 2 / 10 If Earth’s radius increases (mass same), g will Increase Decrease Remain same Double 3 / 10 Relative density of substance having density 500 kg/m³ is 0.5 5 50 500 4 / 10 A stone sinks in water because Its weight < buoyant force Its density < water Its weight > buoyant force Its mass is zero 5 / 10 Acceleration due to gravity at Earth’s surface depends on Earth’s mass Earth’s radius Both mass and radius Air pressure 6 / 10 If mass of Earth increases, value of g will Increase Decrease Remain same Become zero 7 / 10 Two bodies with masses 2 kg and 4 kg are separated by distance r. If distance becomes 2r, force becomes F/2 F/4 F/8 F/16 8 / 10 A body thrown vertically upward slows down because acceleration due to gravity acts Upward Downward Horizontally Randomly 9 / 10 A body sinks when Weight > buoyant force Buoyant force > weight Weight = buoyant force Gravity absent 10 / 10 Mass of a body in relation of the gravity: Changes with location Depends on gravity Depends on height Remains constant Your score is 0% Restart quiz
