The magnetic compass is not useful for navigation near the magnetic poles. Since

Solution: At the magnetic poles, a dip needle stands vertical (dip=90 degrees), the horizontal intensity is zero, and a compass does not show direction. At the north magnetic pole, the north end of the dip needle is down; at the southmagnetic pole, the north end is up. At the magnetic equator the dip or inclination is zero so option C

QUESTION: 27

A lift of mass 1000 kg is moving with an acceleration of 1 m/s2 in upward direction. Tension developed in the string, which is connected to the lift, is

Solution:


The mass of the lift is 1000 Kg , the acceleration of 1 m / s^2 and the acceleration due to gravity is 9.8 m / s^2 .

The tensions developed in strings is given as ,

T = mg + ma

===》 1000 × 9.8 + 1000 × 1

=====》 10800 N

Thus , the tensions developed in strings is 10800 N.
