Question

how to solve this electric field lines chapter​

Answer 1

Answer:

you can solve this by using the formula

F = (q1 q2 )/r^2

here F and r is unknown

so , F1 = (4×2)/r^2 ........(¡)

after collision

F2 = (3×3) / r^2 ...........(¡¡)

now equate this equation (¡) and (¡¡)

you will get the answer
