Two observers moving with different velocities see that a point charge produce same magnetic field at the same point A. Their relative velocity must be parallel to 
where 
is the position vector of point A with respect to point charge. This statement is –
A
True
B
False
C
Nothing can be said
D
True only if the charge is moving perpendicular to the 
Answer
True
Explanation
Solution
B = 
Vo = velocity of charge with respect to observer.
A and B two observer have velocity VA and VB
