JEE Mains Physics Question || Newtons Law of Motion Class 11 IIT JEE

Write short notes on : Dalton's law of partial pressures and its applications.

A block of mass 3 kg which is at rest on a surface is pulled horizontally by a force. If the displacement of the block is 15 m in the first 3 s and the surface offers a resistance of 2 N, find the sequence of steps to calculate the magnitude of applied force. (a) Note down the values of s, u, t and frictional force (b) The applied force on the block is the sum of frictional force and net force (c ) Substitute the values of s, u and t in the equation of motion nad solve for 'a' (d) Using Newton's second law of motion, calculate the net force acting on the block.
