| Directions: In the following questions, a statement of Assertion (A) is followed by a statement of Reason: |
| (R). Mark the correct choice as: |
| Assertion (A): The force with which two charges attract or repel each other are not affected by the presence of a third charge. |
| Reason (R): Force on any charge due to a number of other charges is the vector sum of all the forces on that charge due to other charges, taken one at a time. |
A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
B) Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
C) Assertion (A) is true but Reason (R) is false
D) Assertion (A) is false and Reason (R) is also false
Correct Answer: B
Solution :
(b) Force on any charge due to a number of other charges is the vector sum of all the forces on that charge due to the other charges, taken one at a time. The individual forces are unaffected due to the presence of other charges. This is the principle of superposition of charges.
