Like poles attract each other.

Describe an experiment to show : Unlike charges attract each other.

(A) : If two beams of protons move parallel to each other in same direction then these beams repel each other. (R) : Like charges repel while opposite charges attract each other.

(a) Can two bodies having like charge attract each other (yes/No) (b) Can a charged body attract an unchanged body? (yes/No) (c ) Two identical metallic spheres of exactly equal masses are taken, one is given a positive charge q and the other an equal negative charge. Their masses after charging are different. Co,,ent on the statement.

Can two similarly charged bodies attract each other?

A: Like currents repel and unlike currents attract each other (in conductor). R: Magnetic force acts in the direction of current.

Similar charges attract each other. ____________

Two small bar marnets are placed in a line with like poles facing each other at a certain distance d apart. If the length of each magnet is neglifible as compared to d, the force between them will be inversely proportional to

Two proton beams going in the same direction repel each other whereas two wires carrying currents in the same direction attract each other. Explain.

Two bar magnets are placed close to each other with their opposite poles facing each other. In absence of other forces, the magnets are pulled towards each other and their kinetc energy increases. Does it contradict our earlier knowledge that magnetic forces cannot do any work and hence cannot increase kinetic energy of a system?

The battery discussed in the previous question is suddenly disconnected. Is a current induced in the other loop? If yes, when does it start and when does it end? Do the loops attract each other or repel?
