The force acting on a plastic bucket are: • Gravitational force: It is acting downwards. • Muscular force: It is applied by our hands to lift the bucket in upward direction.

The force acting on a plastic bucket are:
• Gravitational force: It is acting downwards.
• Muscular force: It is applied by our hands to lift the bucket in upward direction.
Although these forces are acting on the bucket but no change is found in its state of motion because the two forces are balancing each other and as a result net force is zero.
The force which is responsible for the attraction between the ball and the wall is electrostatic force. When we rub the balloon by a synthetic cloth, it gets charged. When it is taken near the wall, it will get attracted towards the uncharged wall because of the electrostatic force which is the forcRead more

When we rub the balloon by a synthetic cloth, it gets charged. When it is taken near the wall, it will get attracted towards the uncharged wall because of the electrostatic force which is the force exerted by a charged body on another uncharged body.
When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb, water gets filled in the dropper. The rise of water in the dropper is due to
The rise of water in the dropper is due to (d) atmospheric pressure. https://www.tiwariacademy.com/ncert-solutions/class-8/science/chapter-11/
