JEE Main 2025 — 4 April, Morning Shift — Question 62

In an electromagnetic system, the quantity representing the ratio of electric flux and magnetic flux has

dimension of MPLQTRAS M^{P} L Q T^{R} A^{\text {S }}, where value of ' QQ ' and ' RR ' is

  1. Option A:

    (−2,1)(-2,1)

  2. Option B:

    (1,−1)(1,-1)

    Correct
  3. Option C:

    (−2,2)(-2,2)

  4. Option D:

    (3,−5)(3,-5)

Answer: B

Step-by-step solution

ϕEϕM=EABA=C\frac{\phi_{E}}{\phi_{M}}=\frac{E_{A}}{B_{A}}=C

=LT−1=L T^{-1}
