Question

The earth's magnetic field at a certain place has horizontal component 0.3G and total strength 0.5G. The angle of dip is 

(a) tan^-14/3 

(b) tan^-13/4 

(c ) tan^-15/3 

(d) tan^-13/5

Answer 1

Correct option is : (a) tan^-14/3 

tan^-1(4/3) ; θ = tan^-1 (B_V /B_H) 

B_V =\(\sqrt{B^2-BH^2}\)
