Two identical bar magnets are dropped from equal heights. Magnet A is dropped over bare earth and magnet B over a metal plate. Which magnet strikes first?
A) magnet A
B) magnet B
C) both strike at the same time
D) whichever has its N pole toward the ground
E) whichever has its S pole toward the ground

Respuesta :

The correct answer is C, both magnets will strike at the same time when dropped from equal heights over earth and metal plate.

Why do they both strike first?

Both magnets will strike the ground at the same time, assuming that they are dropped from the same height and there are no other forces acting on them. The fact that one magnet is dropped over a metal plate and the other is dropped over bare earth will not affect their rate of descent. The only factors that determine the rate of descent of an object in freefall are its mass and the acceleration due to gravity. The magnets are identical, so they will have the same mass, and the acceleration due to gravity is a constant value that is the same for both magnets. Therefore, both magnets will fall at the same rate and will strike the ground at the same time.

Hence, the correct answer is that they both strike at he same time.
