  • Assertion :The force with which two charges attract or repel each other are not affected by the presence of a third charge. Reason : 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
    If both assertion and reason are true and reason is the correct explanation of assertion.
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
    C
    If assertion is true but reason is false.
    D
    If both assertion and reason are false.

  • Assertion (A): Force between two point charges at rest is not changed by the presence of the third point charge between them . Reason (R ) : Force depends on the magnitude of the first two charge and separation between them.

    A
    Both `(A)` and `(R )` are true and `'R'` is the correct explanation of `A`.
    B
    Both `A` and `R` are true and `R` is not the correct explanation of `A`
    C
    `A` is true and `R` is false
    D
    `A` is false and `R` is true.
