1.	Interestellar space has an extremely weak magnetic field of the order of `10^(-12)T`. Can such a weak field be of any significant consequence ? Explain.
Answer» When a charged particle moves in a magnetic field, it is deflected along a circular path such that `BeV = (mV^(2))/(r) :. r = (mV)/(Be)` When B is low, r high i.e., radius of curvature of path is very large. Therefore, over the gigantic inter stellar distance, the deflection of charged particles becomes less noticeable.
