A long straight wire of length 2 m and mass 250 g is suspended horizontally in a uniform horizontal magnetic field of 0.7 T. The amount of current flowing through the wire will be (g = 9.8 ): 2.45 A 2.25 A 2.75 A 1.75 A
Multiple Choice Options
- A 2.45 A
- B 2.25 A
- C 2.75 A
- D 1.75 A
Step-by-Step Verified Solution
m g = i _ B 250 _ 10 _ 3 _ 9.8 = i _ 2 _ 0.7 i = 0.250 _ 9.8 2 _ 0.7 = 0.250 _ 7 i = 1.75 A
