manet A has twice the magnetic field strength of magnet B (at equal distance ) and , at a certain distance,it pulls on magnet B with force of 50n. with how much force, then dose magnet B PULL ON MAGNET a?
Think: Newton's third law
35 tons
To find the force with which magnet B pulls on magnet A, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Since magnet A has twice the magnetic field strength of magnet B, it exerts a force of 50 N on magnet B. According to Newton's third law, magnet B will exert an equal and opposite force on magnet A.
Therefore, magnet B will pull on magnet A with a force of 50 N, but in the opposite direction.
