JEE Main 2026 — 2 April, Evening Shift — Question 13

Two point charges 8μC8\mu\mathrm{C} and −2μC-2\mu\mathrm{C} are located at x=2cmx=2\mathrm{cm} and x=4cmx=4\mathrm{cm} respectively on the xx-axis. The ratio of electric flux due to these charges through two spheres of radii 3cm3\mathrm{cm} and 5cm5\mathrm{cm} with their centers at the origin is

  1. Option A:

    4:1

  2. Option B:

    3:4

  3. Option C:

    4:3

    Correct
  4. Option D:

    4:5

Answer: C

Step-by-step solution

For radius 3 cm, enclosed charge = 8μC for radius 5 cm, enclosed = 8-2=6μC flux ratio = 8/6 = 4/3
