Question

If B H = 4 × 10 − 5 T and B V = 2 × 10 − 5 T , then the Earth's total field (in T ) at the place is, 6 × 10 − 5 T, 2 5 × 10 - 5 T, 4 × 10 - 5 T, 3 × 10 - 5 T

MARKS App · Accepted Answer

Given: B H = 4 × 10 − 5 T , B V = 2 × 10 − 5 T . The total earth's magnetic field B at the given place is B = B V 2 + B H 2 = ( 4 2 + 2 2 ) × 10 − 5 T = 20 × 10 − 5 T = 2 5 × 10 − 5 T
