What is the meaning of starlight?
Correct option is A)
Given, mass of the wire =200g=0.2kg
Length of the wire =15m
Current i=2A
Magnetic field B=?
The force acting on the current carrying wire in uniform magnetic field
F=Bilsinθ
F=Bil (∵θ=90
o
)
Weight of the wire w=mg=0.2×9.8N
In the position of suspension
Bil=mg
B=
il
mg
=
2×15
0.2×9.8
=0.65T
This is your answer.
