A closed loop PQRS carrying a current is placed in a uniform magnetic field. If the magnetic forces on segments PS, SR and RQ are F1, F2 and F3 respectively and are in the plane of the paper and along the directions shown, the force on the segment of QP is

• F3 - F1-F2

• F3 - F2 + F1

B.

F4 sinÂ Î¸ = F2
F4 cosÂ Î¸ = (F3-F1)

F4 sinÂ Î¸ = F2
F4 cosÂ Î¸ = (F3-F1)

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.Â

So, the apples fall down.Â
