Magnetic Effects Of Current Question 169
Question: 3 A of current is flowing in a linear conductor having a length of 40 cm. The conductor is placed in a magnetic field of strength 500 gauss and makes an angle of $ 30{}^\circ $ with the direction of the field. It experiences a force of magnitude [MP PET 1993]
Options:
A) $ 3\times 10^{4},newton $
B) $ 3\times 10^{2},newton $
C) $ 3\times {{10}^{-2}},newton $
D) $ 3\times {{10}^{-4}},newton $
Show Answer
Answer:
Correct Answer: C
Solution:
$ F=Bil\sin \theta $ $ =500\times {{10}^{-4}}\times 3\times (40\times {{10}^{-2}})\times \frac{1}{2}=3\times {{10}^{-2}}N $
