Spring balance is used to measure:
Volume
Density
Force
Pressure
Sharp surfaces may :
Increase pressure
Increase force
Decrease pressure
Decrease force
The force which acts in the direction opposite to the direction of motion is called :
Gravitational Force
Magnetic Force
Frictional Force
Electrostatic Force
Two coolies push a baggage trolley. One applies 100N force and the other applies 200N force in the same direction. The net force is :
200N
300N
20N
