Q. If a rigid body is rotating about an axis passing through the point 2i^-j^-k^ and parallel to I^-2j^+2k^ with an angular velocity 3 radians/sec, then find the velocity of the point of the rigid body whose position vector is 2i^+3j^-4k^.
a) -2i^+3j^+4k^
b) 2i^-3j^+4k^
c) -2i^+3j^-4k^
d) -2i^-3j^-4k^
