Physics MCQs Solutions

All the given options for “If we release a magnet held in our hand, it falls to the ground. The force responsible for this is” are incorrect. The correct answer is Gravitational Force.
The pressure exerted by a brick on the table would be equal in all cases.
The correct values for normal atmospheric pressure are 101.3 kPa and 760 mm of Mercury.
When a batsman hits a moving cricket ball, the change that happens appreciably is speed and direction.
If a force of 150 N is applied to an area of 3 m^2, the pressure will be 150 N / 3 m^2 = 50 N/m^2.
