Concept of pseudo force is valid only ina)inertial frameb)Non-inertial...
This is because newton's laws are valid only for inertial frames. Analysis from an inertial frame isn't possible using those laws, to put it simple.
Let us assume a glass lift is going up with an acceleration 'a'. with respect to the ground. Clearly, this is a non-inertial frame as it has an acceleration. Man 'A' is inside the lift and wants to analyze the motion of the lift, but he cannot, as the newton's laws are not valid. So he takes his phone and calls Man 'B', who stands outside on the ground (in an inertial frame). This fellow watches Man 'A' go up with acceleration 'a'. Forces acting on Man 'A' are:
1. Weight, mg
2. Normal reaction offered by the lift, N
Thus, taking upward direction as positive and using Newton's Law, he writes the equation,
N - mg = ma, or
N = mg+ma
He tells "N=mg+ma" on phone to Man 'A'.
Now, Man 'A' looks around himself. According to himself, he is at rest. So, according to him, N = mg. Sadly, he knows this is not a correct analysis, as the newton's laws can't be applied!
The correct analysis, as received on phone, is N=mg+ma!
This is his eureka moment! He realizes that if he considers a "pseudo force" of magnitude 'ma' acting in opposite direction to acceleration of his frame, a correct analysis is possible!
This is why the concept of pseudo force is introduced, although it isn't necessary. You can always equate the net force in a direction equal to mass times acceleration from outside the non-inertial frame. However, if you want to do it from the non-inertial frame, the result can be interpreted in such a way, which suggests that the body is under rest, but an additional force (pseudo force) is acting.

Concept of pseudo force is valid only ina)inertial frameb)Non-inertial...
Explanation:
Non-inertial Frame:
Pseudo force is a concept that is valid only in a non-inertial frame of reference. A non-inertial frame is a frame of reference that is accelerating or rotating with respect to an inertial frame.
Inertial Frame:
In contrast, an inertial frame is a frame of reference in which Newton's laws of motion are valid without the need to introduce any extra forces like pseudo forces. In an inertial frame, objects move with a constant velocity unless acted upon by an external force.
Validity of Pseudo Force:
When we analyze motion in a non-inertial frame, the acceleration of the frame itself can cause apparent forces to appear, known as pseudo forces. Pseudo forces are introduced to account for the fact that an observer in a non-inertial frame would see objects accelerating even when no external forces are present.
Conclusion:
Therefore, the concept of pseudo force is essential in non-inertial frames to accurately describe the motion of objects within those frames. In inertial frames, pseudo forces are not necessary as objects follow Newton's laws without any additional fictitious forces.
Non-inertial Frame:
Pseudo force is a concept that is valid only in a non-inertial frame of reference. A non-inertial frame is a frame of reference that is accelerating or rotating with respect to an inertial frame.
Inertial Frame:
In contrast, an inertial frame is a frame of reference in which Newton's laws of motion are valid without the need to introduce any extra forces like pseudo forces. In an inertial frame, objects move with a constant velocity unless acted upon by an external force.
