The correct answer is " Pressure is measured as force per unit area".

Explanation:

Pressure is defined as the force per unit area.

The expression for the pressure is as follows:

Here, F is the applied force and A is the area.

The pressure is inversely proportional to the area. More the area, lesser will be the pressure. Lesser the area, more will be pressure.

For example, the area of the strap of the school bag is more so that there will be less pressure on the students's shoulder.

Therefore, the correct option is (c).

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
