JEE Main 2 April 2026, Shift 2, Physics Q37

Question 37 of 75 in this shift, Physics question 12 of 25, Section A.

An electromagnetic wave travels in free space along the xx-direction. At a particular point in space and time, B⃗=2×10−7j^\vec{B} = 2 \times 10^{-7}\hat{j} T is associated with this wave. The value of corresponding electric field E⃗\vec{E} at this point is
