AJoule, the unit of energy of a body
BNewton, the unit of force on a body
CPascal, equal to 1 newton per sq metre
DWatt, the unit of power of a device
Answer & Solution
Correct answer: C. Pascal, equal to 1 newton per sq metre
1. Pressure = force / area.
2. Force in newtons divided by area in square metres gives N/m^2.
3. This unit is named the pascal.
4. So option A is correct.
