Question

The magnetic field in a travelling electromagnetic wave has a peak value of 20 nT. The peak value of electric field strength is (A) 3V/m (B) 6 V/m (C) 9 V/m (D) 12 V/m

Tardigrade Admin · Accepted Answer

Peak value of electric field E0 = B0c = 20 × 10-9 × 3 × 108 = 6 V/m

Q. The magnetic field in a travelling electromagnetic wave has a peak value of $20 n T$ . The peak value of electric field strength is

$3 V / m$

$6 V / m$

$9 V / m$

$12 V / m$

Peak value of electric field
$E_{0} = B_{0} c = 20 \times 1 0^{- 9} \times 3 \times 1 0^{8} = 6 V / m$
