Write Coulomb's law in vector form for the force of attraction or repulsion between two point charges.
Q.
Assertion : Magnetic force between two short magnets, when they are co-axial follows inverse square law of distance.
Reason : The magnetic forces between two poles do not follow inverse square law of distance
Q.
The force of attraction between two unlike magnetic poles varies inversely as the square of distance between them. When the distance two poles is 10 cm. the force of attraction is 2 Dynes. Find the force of attraction between the same two poles when the distance between them is 5 cm.
Q.
Assertion(A): Repulsion is the sure test for magnetism.
Reason(R): Attraction can occur between two unlike poles of a magnet and also between a magnet and a magnetic material.
