Four charges Q(1),Q(2),Q(3) and Q(4) of ...

Four charges `Q_(1),Q_(2),Q_(3)` and `Q_(4)` of same magnitude are fixed along the X- axis at x = -2a,a+a and +2a respectively . A positive charge q is placed on the positive Y - axis at a distance `b gt 0` . Four options of the signs of these charges are given in Column- I . The direction of the forces on the charges q is give in Column - 2 . Match Column - I with Column - II and select the correct answer using the codes given below the columns.

A

P-3, Q-1, R-4, S-2

B

P-4, Q-2, R-3, S-1

C

P-3, Q-1, R-2, S-4

D

P-4, Q-2, R-1, S-3

Text Solution

Verified by Experts

The correct Answer is:
A
When all are positive net field is along +y axis `P rarr 3`

when `Q_(1), Q_(2)` positive `Q_(3), Q_(4)` negative `Q rarr 1`

When `Q_(1), Q_(4)` positive and `Q_(2), Q_(3)` negative `R rarr 4`
