it is applied just to solve problems thats it
well to find out the actual force on a body
we do it
if u r on a non inertial ref frame u ll nt be able to find actual force...isliye we apply pseund by doing so u get the actual force on the body
if u r sitting in a car and you experience an outward F (and smash ur face on the windows) when the car is turning right??
WHAT THE HELL IS THAT FORCE???
its centriFUGAL force, which is a pseudo force.
so, pseudo forces are valid in non inertial frames (such as turning car) and IN THAT FRAME, ther ARE REAL!!!!!!!!!!!!
see, in the question 1, it is said "without dislodging the dishes"
is u consider the cloth frame, the dishes are dislodged (moved wrt the cloth). So, i think it is already implied by that, that they r talking about ground frame. (ie. the dishes are dislodged in the cloth frame, so the question of taking that as ur frame is itself wrong in this q)
Once it is ground frame, it is clear na? No pseudo F nothin, so it has to be only inertia...
do u think im correct? yes? oh! then do RATE me...
Please clarify your argument. Which frame of reference are you taking into account and which force is Pseudo force balancing ?
From the frame of reference of table cloth, a Pseudo force is acting on the dishes,because they do not move from ground frame. Very True. But then, what is causing this Pseudo force to act ??
Here you need to understand the concept of Pseudo force. It is not an actual force. It is a consequence of inertia. Inertia tries play it's role to stop the dishes from moving. But in a non inertial frame, a Pseudo force has to be considered in order to explain that inertia on the ground frame. The Pseudo force that a person in an accelerating frame see is originated by the virtue of his being accelerated. Nobody applies it, but it comes side by side with an accelerating frame. Or in order to co-relate different non-inertial frames, the effects of an accelerated frame are explained by introducing an imaginary force, called the Pseudo force.
It's inertia from Ground. And on Table, it's the Pseudo force which originated to explain inertia on the ground. So the basic concept is Inertia only. Pseudo force is only to help us understand a law of Physics in a non accelerating frame as observed from an accelerating frame.
Rate me if you find it useful or knock me back if you are still in trouble.
