Why he did not consider parallel force?Will parallel component of electric field not produce electric pressure on the surface?
Shear force will be responsible for surface tension, as he said in the video. Pressure will be due to the force normal to the area.gracy said:You mean shear force does not exert pressure?
Electric pressure on a charged surface is the force per unit area exerted by an electric field on a charged surface. It is caused by the repulsive forces between the charges on the surface and the external electric field.
The electric pressure on a charged surface can be calculated using the equation P = ε0E², where P is the electric pressure, ε0 is the permittivity of free space, and E is the electric field strength.
The electric pressure on a charged surface is directly proportional to the square of the electric field strength. This means that as the electric field strength increases, the electric pressure also increases.
The electric pressure on a charged surface can cause charged particles to repel each other, creating a repulsive force that can affect their movement and behavior. It can also cause charged particles to align themselves in a particular direction, depending on the direction of the external electric field.
The electric pressure on a charged surface can be affected by several factors, including the strength and direction of the external electric field, the distance between the charged surface and the source of the field, and the properties of the material of the charged surface, such as its permittivity and charge distribution.
