T/F Pressure is defined as force per unit area if the surface.The SI unit of pressure , pascal is shown below:
1 pa = `1Nm^(-2)`

A force of 200 N acts on an area of 1cm^2 uniformly . Find the pressure in Pascal.

Given that force is given F=Pt^(-1)+Qt . Here t is time. The unit of P is same as that of

STATEMENT-1 : Compressibility factor for hydrogen varies with pressure with positive slope at all pressures . STATEMENT-2 : Even at low pressures, repulsive forces dominate in hydrogen gas .

Electric field is the electrostatic force per unit charge acting on a vanishingly small test charge placed at that point. It is a vector quantity and the electric field inside a charged conductor is zero. Electric flux f is the total number of electric lines of force passing through a surface in a direction normal to the surface when the surface is placed inside the electric field We have a Gaussian of radius R with Q at the centre then
