Question

Find the magnitude of the force of the upper magnet on the lowermagnet.
What is the magnitude of the normal force of the table on the uppermagnet?
What is the magnitude of the normal force of the table on the lowermagnet?
What is the normal force of the ground on the table?

Explanation / Answer

the magnitude of the force of the upper magnet on the lower magnetis magnetic force on the lower magnet => F12=3,81.5,67 = 21,6 N the magnitude of the force of the lower magnet on the upper magnetis the same as the magnitude of the force of the upper magnet onthe lower => F21= F12=21,6 N the magnitude of the normal force of the table on the uppermagnet: N1= P1+F21 = 3,81 + 21,6 = 25,41 N the magnitude of the normal force of the table on the lowermagnet: N2= F12- P2 = 21,6-3,81 =17,19 N the normal force of the ground on the table: N= 28,6+3,81.2 = 36,22 N
