Unit of pressure in SI unit is ________.
N / m
m / N2
N / m2
m / N
Turning effect of force is ________.
torque
moment of force
balancing moment
couple
Moment can be calculated using the equation:
M = F × d
M = F / d
M = F2 × d
M = F / d2

force of 1 N on an area of 1 m2
force of 1 kgf on an area of 1 m2
force of 1 N on an area of 1000 m2
force of 1 N on an area of 1 cm2
A syringe works due to ______.

Two boys exert force of 40 N and 60 N in opposite directions on an object. The magnitude of the resultant force is ________.
20 N
200 N
40 N
240 N
Formula for calculating Pressure is:
Pressure = Thrust / Area
Pressure = Thrust × distance
Pressure = Thrust × distance
Pressure = Area / Thrust
