Force = i ( l x B)
where i is current
l is the length of wire
B is the magnetic field...
x is cross product..
1pranav,dont u think we need to know the direction in which the wire is carrying the current,it is not specified here.
say if the conductor is parallel to the field,force eill be zero otherwise the magnitude will vary with the angle between the length of conductor and the field.
29Use the formula..current is in +x direction..
I x ( i + j + k ) = - j + k
so force = B ( -j + k )
