<u>Answer:</u>
The correct answer option is: they are equal and opposite.
<u>Explanation:</u>
A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.
And according to the Newton's third law: for every action, there is an equal and opposite reaction.
For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.
Answer:
therefore critical angle c= 69.79°
Explanation:
Canola oil is less dense than water, so it floats over water.
Given 
which is higher than that of water
refractive index of water 
to calculate critical angle of light going from the oil into water
we know that

now putting values we get

c= 
c=69.79°
therefore critical angle c= 69.79°
Net force
