Dimensions of pressure are same asA) Force per unit areaB) P.E. per unit volumeC) K.E. per unit of volumeD) All of the above

The dimensions of pressure are the same as Force per unit area. So, the correct answer is A) Force per unit area.

Here's why:

Pressure is defined as the amount of force applied per unit area. In terms of SI units, pressure is measured in Pascals (Pa), which is equivalent to one Newton (the unit of force) per square meter (the unit of area). Therefore, the dimensions of pressure are the same as those of force per unit area.

Potential Energy (P.E.) per unit volume and Kinetic Energy (K.E.) per unit volume have different dimensions than pressure, so options B and C are incorrect.

Therefore, option D, "All of the above," is also incorrect.
