In an electromagnetic system, the quantity representing the ratio of electric flux and magnetic flux has the dimension of MP LQ TR AS, where the values of 'Q' and 'R' are

Asked in JEE Main 4th April 1st Shift 2025 · Units and dimensions of flux

Answer: (1) (1, –1)

Step-by-step solution

Electric flux φ_E = EA = [ML³T⁻³A⁻¹].

Magnetic flux φ_B = [ML²T⁻²A⁻¹].

The ratio is [L T⁻¹], i.e.

M⁰L¹T⁻¹A⁰. So Q = 1 and R = -1.

Why the other options are wrong
