Pressure:
The force per unit area is called……………….
a) density
b) strain
c) pressure
d) none of these
If the force is applied on area ‘A’ then pressure is…..
a) p=FA
b) P=F/A
c) none
d) both a & b
The S.I unit of pressure is………….….
a) atm
b) N.m
c) bar
d) pascal
Explanation: The S.I unit of pressure is Pascal (Pa).
1Pa=………..
a) N
b) N.m
c) N/m
d) N/m2
Explanation: P=F/A So 1Pa =1N/1m2
The pressure is…………if the force applied to a given area is increased.
a) decrease
b) increase
c) constant
d) remains same
Explanation: pressure has a direct relation with applied Force. As P=F/A, So with when force increases pressure also increases.
