Question
For two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
  1. Both A and R are true, and R is the correct explanation of A.
  2. Both A and R are true, but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false and R is also false.
Assertion (A): A point charge is brought in an electric field. The field at a nearby point is increase, whatever be the nature of the charge.
Reason (R): The electric field is independent of the nature of charge.
✓

Answer

  1. A is false and R is also false.
Explanation:

Electric field at the nearby point will be resultant of existing field and field due to the charge brought. lt may increase or decrease if the charge is positive or negative depending on the position of the point with respect to the charge brought.

Assertion: Two electric bulbs of $50$ and $100$ watt are given. When connected in series $50$ watt bulb glows more but when connected in parallel $100$ watt bulb glows more.
Reason: In series combination, power is directly proportional to the resistance of circuit. But in parallel combination, power is inversely proportional to the resistance of the circuit.
