Force and pressure

Force is a push or pull which helps in changing of an object

• position

• direction

• shape

• all of them

Force acting per unit area

• density

• pressure

• volume

• thrust

in the adjoining figure at which point is the pressure maximum

• at point A

• at point B

• at point C

• none of them

Forces acting in the same direction on an object gets

• diminished

• divided

• added

• subtracted

What happens to the speed of an object if the applied force acts in the direction of the motion of the object

• decreases

• increases

• remains same

• changes its direction

What will be the speed of the object if it is at rest

• infinite

• zero

• very high

• very slow

Which force/ forces acts while holding a bucket of water

• magnetic force

• muscular force

• gravitational force

• both b and c

What happens to the speed of an object if the applied force acts in the direction opposite to the direction of motion of an object

• decreases

• increases

• remains same

• all may be true

Why a ball rolling on the floor stops after some time

• ball becomes light

• due to friction

• ball becomes heavy

• due to gravitational force

North pole of a bar magnet repels the north pole of another bar magnet. the force acting is

• non contact force

• contact force

• gravitational force

• muscular force
