A) (1)and (3)
B) (3) and (4)
C) (2) and (3)
D) (2) and (4)
Correct Answer: C
Solution :
Both \[\overset{\to }{\mathop{\mathbf{B}}}\,\] and \[\overset{\to }{\mathop{\mathbf{E}}}\,\] should be along the direction of velocity and both \[\overset{\to }{\mathop{\mathbf{B}}}\,\] and \[\overset{\to }{\mathop{\mathbf{E}}}\,\] are mutually perpendicular and perpendicular to the direction of velocity.You need to login to perform this action.
