we know the formula F=macos theta. and F=mue*mg.from this u can find the force and equal both and find out accelaration

the answer is 200N. i did i have take one crate and i calculated the force.according to the force exerted by one is exactly opposite to anothor

the first case is right i think but i didn't understand the second case completely the given figures are not clear

due to passing of current the magnetic field is created in the rods hence we know the formula F=vlb from that u can find the force and from F=kx u can find the spring constant

yes u r correct
