What length would observer measure for the tube

Reference no: EM13268933

An electron of ? = 0.999 993 moves along the axis of an evacuated tube that has a length of 2.69 m as measured by a laboratory observer S at rest relative to the tube. An observer S' at rest relative to the electron, however, would see this tube moving with speed v (=?c). What length would observer S' measure for the tube?
