Q.6. Assertion : When bodies are charged through friction, there is a transfer of electric charge from one body to another, but no creation or destruction of charge.
Reason : This follows from conservation of electric charges.
Q.31. Assertion (A): Three equal charges are situated on a circle of radius r such that they form on equilateral
triangle, then the electric field intensity at the centre is zero.
Reason (R): The force on unit positive charge at the centre, due to the three equal charges are represented
by the three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero.
