Tangent Law And Galvanometer QUESTIONS AND ANSWERS

Basic Science : Tangent Law And Galvanometer QUESTIONS AND ANSWERS :: part1 : 11 to 15

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

11.A tangent galvanometer is an absolute instrument because

it uses a small magnetic needle

it measures earth’s magnetic field

it is sensitive around 45°

it does not take the help of other instruments for calibration

12.A current of 1.5A flows through the coil of 5 turns of a tangent galvanometer having a diameter 0.3m. If the deflection of the needle at its centre is 45°, then the horizontal intensity of earth’s field at that place is

250 A-turn/m

25 A-turn/m

2.5 A-turn/m

2500 A-turn/m

13.The tangent galvanometer is used to determine

potential difference

deflection

resistance

current

14.The plane of the compass box of a tangent galvanometer is

along the magnetic meridian

parallel to the turn table

parallel to the plane of the coil

vertical

15.The magnetic field along the axis of a bar magnet is

B = µ0/4π . 2Md/(d2-l2)3/2

B = µ0/4π . M/(d2+l2)3/2

B = µ0/4π . 2Md/(d2-l2)2

B = µ0/4π . M/(d2+l2)2
