A body is weighed by a spring balance to be 1000N at the north pole. How much will it weight at the equator. Account for rotationof earth only.
1 AnswersThe centrifugal forces will be acting on the particle at the equator but not on the poles (as the poles have 0 angular velocity).
As such the Weight will be reduced by mv2/R and becomes (mg - mv2/R) at the equator, where v is the linear velocity of the earth and R is the radius of the earth
But it remains mg at the poles.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
