IIT JEE : Magnetic Effect Of Current And Magnetism QUESTIONS AND ANSWERS :: part2 : 1 to 5

Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2024 examinations :

1.If the p. d. between two plates separated by a distance d be V, then electric field E is equal to

Vd
d / V
1 / Vd
V/ d

2.A charged particle moves through a magnetic field in a direction perpendicular to it, then

the speed of the particle remains unchanged
the direction of particle remains unchanged
acceleration remains unchanged
velocity remains unchanged

3.A length of wire carries a steady current. It is bent to form a circular coil of one turn only. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field at the centre caused by the same current is

A half of its first value
Unaltered
A quarter of its first value
Four times its first value

4.The magnetic induction at a point due to a long straight conductor carrying current is independent of

its length
the current coil
the distance from the given point
all of the above

5.A vertical straight conductor carries a current vertically upwards. A point P lies to the east of it at a it at the same distance. The magnetic field at P is

greater as at Q
same as at Q
less than at Q
greater or less than at Q depending upon the strength of the current
