(A)
the direction of field B⃗ will be same as the direction of velocity ν⃗
-
(B)
the direction of field B⃗ will be opposite to the direction of velocity ν⃗
-
(C)
the direction of field B⃗ will be perpendicular to the direction of velocity ν⃗ .
-
(D)
the direction of field B⃗ does not depend upon the direction of velocity ν⃗
✅ Correct Answer: (C)
the direction of field B⃗ will be perpendicular to the direction of velocity ν⃗ .
