A person of mass 50 kg stands on a weighing scale on a lift. If the lift is descending with a downward acceleration of 9 ms-1 , what would be the reading of the weighing scale? ( Take g =10 ms-2 )

since it is Non inertial frame so will have to apply pseudo force in opposite direction Reading of the weighing scale = Mg - Ma = M(g - a) = 50 ( 10 - 9) = 50 N Note:- the unit of acceleration is incorrect it should be m/sec2

The Earth moving round the Sun in a circular orbit is acted upon by a force, and hence work must be done on the Earth by this force. Do you agree with this statement?
The force on earth jn circular trajectory is gravity,acting radially inward...the direction of motion is tangential.....as u knw work is dot product of force and dx, the work done is zero.

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.
