let me try this

This is the diagram given for the problem. Now I was able to identify, that the fact that the capacitance of a spherical capacitor, with...

ok that makes sense. but I have a question. IF there was no external torque (hypothetical) then is it valid to conserve momentum as I...

I have another question: If angular momentum is conserved, then it would be conserved in all directions. But in the horizontal...

Consider the diagram shown above. I came up with two ideas to solve this: i) I do not see any external torques about the vertical axis...

so are you implying, that the value of F I got using force balance, IS a valid value for some a force to get the block moving? but it's...

but when velocity is maximum, there is a momentary equilibrium, isn't it? this means forces at that point of time will be balanced. is...

why is this? why not the eqb. position?

When the acceleration is maximum, the velocity will be zero, and vice verca. I'm aware of this. But how is it going to help in this case?

Well, force balance leads to the answer: ##F= μg(m_1 +m_2)##using work done (energy balance equation) leads to ##F= μg(m_2 + 2m_1)/2##...

When F is large enough to move m1, m1 will start with some acceleration, such that F>kx+friction where x is the elongation in the...

The diagram above describes the situation. Say the spring constant is k. The main goal will be to apply the condition that when the...
