Hi Thank you for your answer. My unsuccessful solution: lets take the length l, for r<R, why?

Homework Statement An infinitely long insulating cylinder of radius R has a volume charge density that varies with the radius as given by the following expression where ρ0, a, and b are positive constants and r is the distance from the axis of the cylinder. Use Gauss's law to determine the...

all right, thank you both :)

Homework Statement the small block is heading towards the uniform vertical rod. the rod is pivoted at its midpoint and is free to rotate without friction. the block collides with the rod, which is at rest, and sticks to it at its lower point. find the angular speed of rod immediately after...

Homework Statement A solid sphere of mass m and radius r rolls without slipping along the track shown below. It starts from rest with the lowest point of the sphere at height h above the bottom of the loop of radius R, much larger than r. (Consider up and to the right to be the positive...
