Thank you. I will refer to it and try it now.

Will the charge distribution over the whose surface area of the sphere be uniform or non uniform?

Homework Statement Consider a thin conducting shell of radius r carrying total charge q. Two point charges q and 2q are placed on the points A and B which are at the distances 0.5r and 2r from centre of the shell respectively. If the shell is earthed how much charge flows from to the earth...

Nope. But thanks for the reply. I will refer to it and try it out.

Homework Statement Given there is a conducting sphere which has a charge q on it. A plane cuts the sphere into 2 form a distance r from centre. How can we calculate the electrostatic force on one part on either side of the plane due ro the other part? Homework EquationsThe Attempt at a...

Thanks you so much!

Homework Statement A light uniform spring is tied between the ceiling and the floor keeping the spring vertical as shown in the figure. A bead of finite mass is glued at a distance l from the upper end and then allowed to go slowly down. The bead shifts a distance y.How does the y depend on...

so is it necessarily true that calculating it with force equations is 100% wrong?

Can you please clarify when should i use this logic and when should i use the force equation? Because i have been greatly confused as i first saw it as a standard pendulum problem with varying forces.

But as per the solution we need to take net acceleration every instance 0. Why is it so? Why is it wrong to do that the rate of change of the given velocity is its acceleration and thus the forces along it should be giving it?

Homework Statement Two small equally charged spheres, each of mass m, are suspended from the same point by silk threads of length 1. The distance between the spheres x << 1. Find the rate dqldt with which the charge leaks off each sphere if their approach velocity v = a/ √x, where a is a...

Homework Statement A horizontal disc is rotating with an angular velocity w about its axis perpendicular to its plane. A small body of mass m moves with velocity v relative to the disc alog the diameter. Find the net force exerted by the disk on the body as function of radius from centre...

Homework Statement A small disk A is placed on an inclined plane forming an angle (alpha) with horizontal and is imparted an initial velocity v. Given coefficient of friction =k and ant initial moment angle of velocity =90 degrees. Find out how long it takes to come ro rest and give the...

The constant @harsuspex said is it mgμ?

Thank you. I also tried doing that way but stopped because i was confused by the problem. I will work in this direction further now
