Ans Pressure can be given by the formula, \P=\frac{F}{A}\ Pressure is inversely proportional to the surface area on which the force is acting The smaller is the surface area, the larger will be the pressure on the surface on which the force is being acted upon W=mg\ Where, \m=\Mass of the body \g=\Acceleration due to gravity TheAnswer (1 of 19) First the mathematical expression here is as follows F f = ma, where F is the horizontal force you are wanting Since the surface poses a friction, f, the net force on the box should be F f So that's equal to ma Now f = mgk, where m is the mass, g is the acceleration due
