Tangent Law And Galvanometer QUESTIONS AND ANSWERS

Basic Science : Tangent Law And Galvanometer QUESTIONS AND ANSWERS :: part2 : 1 to 5

Following Basic Science multiple choice objective type questions and answers will help you in many types of 2024 job and other entrance examinations :

1.In Tan A position of equal distance method of comparing the magnetic moments of bar magnets, the ratio of their moments is given by

M1/M2 = (d2+l12)2 tan θ1/ (d2+l22)2 tan θ2

M1/M2 = (d2+l12)3/2 tan θ1/ (d2+l22)3/2 tan θ2

M1/M2 = (d2-l12)2 tan θ1/ (d2-l22)2 tan θ2

M1/M2 = (d2-l12)3/2 tan θ1/ (d2-l22)3/2 tan θ2

2.In Tan B position of equal distance method of comparing magnetic moments of bar magnets, the ratio of their moments is given be

M1/M2 = (d2+l22)3/2 tan θ1/ (d2+l12)3/2 tan θ2

M1/M2 = (d2+l12)3/2 tan θ1/ (d2+l22)3/2 tan θ2

M1/M2 = (d2-l12)2 tan θ1/ (d2+l22)2 tan θ2

M1/M2 = (d2+l12)2 tan θ1/ (d2+l22)2 tan θ2

3.For a short placed across the arms of deflection magnetometer in tan B position

M/B = d3/2 .tan θ  107

M/B = 10-7 d3 tan θ

M/B = d3 tan θ  107

M/B = 10-7.d3/2 .tan θ

4.In Tan A position of null deflection method of comparing the magnetic moments of bar magnets, the ratio of their moments is given by

M1/M2 = (d12-l12)2 d2/ (d12-l22)2 d1

M1/M2 = (d12-l12)2 d1/ (d12-l22)2 d2

M1/M2 = (d12+l12)2 d1/ (d12+l22)2 d2

M1/M2 = (d12+l12)2 d2/ (d22-l22)2 d1

5.The deflection of magnetic needle produced by two short magnets are 30° and 60° respectively when the magnets are placed at the same distance along the ration of their magnetic moments is

1:2

2:1

3:1

1:3
