If the mass of a body is 10 kg, what is its weight on Earth? (Take g = 10 m/s²)
What happens to the gravitational force between two masses if the distance between them is doubled?
If the mass of the earth is M and its radius is R, the acceleration due to gravity g is given by:
A hydraulic lift has pistons of area 2 m² and 10 m². If 100 N is applied to the small piston, what is the force on the large one?
The density of a substance is 2500 kg/m³. Its relative density is:
An object weighs 10 N in air and 8 N when fully immersed in water. What is the upthrust acting on it?
Liquid pressure at a point inside a liquid does NOT depend on:
A car starts from rest and reaches a speed of 20 m/s in 5 seconds. If its mass is 1000 kg, the net force is:
Two masses are 10 kg and 20 kg, separated by 2 m. The gravitational force between them is (G is universal constant):
The state of a body when the net force acting on it is zero and it is falling under gravity is called:
What is the mass of an object whose weight is 49 N on Earth? (g = 9.8 m/s²)
When a body is partially or fully immersed in a fluid, it experiences an upward force equal to the weight of the fluid displaced. This is:
Calculate the pressure exerted by a column of water 10 m high. (Density of water = 1000 kg/m³, g = 10 m/s²)
If a body floats in water with half its volume submerged, its density is:
