Question

earth's magnetic field at a place where angle of dip is 37 degree and a vertical component of earth's magnetic field is 0.5 g is

Answer 1

Explanation:

Correct option is C)

Given: Dip θ = 37°

Vertical component V= 0.5 G

To find: Earth’s magnetic field B

Solution :

If θ is the angle of the dip, then

tan θ=

H

V

We know,

tan θ=

4

3

∴H =

tanθ

V

=

4

3

0.5

= 0.67 G

Now

B

total

=

V

2

+H

2

=

0.5

2

+0.67

2

=0.83 G

Hence C option is correct
