Answer» Answer: PHYSICS A current 1A is FLOWING in the sides of EQUILATERAL TRIANGLE of SIDE 4.5×!0 −2 m. The magnetic induction at centroid of the triangle is question
December 26, 2019 avatar Suseela Kankate Share Save ANSWER Magnetic field at the centroid is given by, B=3 4πa μ 0
I
(sinθ 1
+sinθ 2
) Here, θ 1
=θ 2
=60 Length =4.5×10 −2 m a= 2 1
cot60 = 2 3
4.5×10 −2
Therefore, B= 4.5×10 −2
3×10 −7 ×1×2 3
2 2 3
=4×10 −5 T B=4×10 −5 T Explanation: please mark it brainliest answer and please don't forget to give me a thanks for this answer and follow me also |
