between all the choices given is the third choice or letter C. I am hoping that
this answer has satisfied your query about this specific question.
Answer:
Force of static friction between the two surfaces
Explanation:
When two surfaces come into contact, they exert a force that resist the sliding of the two surfaces. This force is called static friction.
This force is given by the relation

Where,
μ - coefficient of static friction
η - normal force acting on the body
When a force acts on a body placed on a rough surface, it doesn't do any work if the applied force was less than the force of static friction.
So, in order to move the body, the applied force should be greater than the force of static friction.

Answer:
1088.9N/m2
Explanation:
Calculation for What pressure is exerted
First step is to find the area of bottom of the tank using formula
Area=Width*breadth
Let plug in the formula
Area=0.5*0.9
Area=0.45m2
Now let calculate what pressure is exerted using this formula
Pressure=Force/Area
Where,
Force=Mass *Gasoline
Area=Width of the tank* Length of the tank
Let plug in the formula
Pressure=50*9.8/0.5*0.9
Pressure=490/0.45
Pressure=1088.9N/m2
Therefore What pressure is exerted is 1088.9N/m2
