One of the properties of the earth's magnetic field is that the
north pole lies in the northern hemisphere
geographic and magnetic meridians coincide
earth's magnetic flux is entirely horizontal at a place where the magnetic dip is zero
earth's magnetic flux is entirely vertical at a place where the magnetic dip is zero

5.1N
7.1N
14.0N
19.6N
Correct answer is D
\(\frac{F_1}{F_2}\) = \(\sqrt\frac{T_1}{T_2}\)
\(\frac{250}{350}\) = \(\sqrt\frac{10}{T_2}\)
T2 = 19.6N
106Hz
213Hz
318Hz
425Hz
Correct answer is A
\(\lambda\) = 4L
= 4 x 80 = 320cm
Converting 320cm to m, we have 3.2m
F = \(\frac{V}{\lambda}\)
= \(\frac{340}{3.2}\)
= 106.25Hz
\(\approxeq\) 106Hz

Correct answer is D
\(\lambda\) = 4(L + C) ; where C = o
\(\lambda\) = 4 x 20 = 80cm
V = \(\lambda\)F
= 80 x 10-2 x 480 = 384ms-1
