Can you find on the wire without finding force on its individual sections by finding `vec(l)` ?

Can you find the mass of sun without weighing?

What is the magnetic force acting on the finite wire due to the fixed infinite wire shown here? Strategy: We cannot use formula vec(F) = i vec(l) xx vec(B) to find the force as the magnetic field created by the fixed infinite wire is non-uniform. We have to consider an element on the finite wire, find force on it and integrate to obtain the net force.

A wire of length L and radius r is clalmped rigidly at one end. When the other end of the wire is pulled by force f, its length increaes by l. Another wire of the same material of length 2 L and radius 2 r, is pulled by a force 2 f. Find the increase in length of this wire.
