## A) Two charges +4esu and +9 esu are situated at a distance of 10 cm . A unit charge is situated at a point on the line joining the charges.  At what point the unit charge experiences a force which is  (a) equal and opposite,(b)equal and in the same direction? B) Two conductors have resistance R1 and R2 at 0°C. Their temperature coefficients of resistances are a1 and a2 respectively.  Show that the temperature coefficients of their equivalent resistances when joined in series and in parallel are respectively   (R1a1+R2a2)/(R1+R2) and (R1a2+R2a1)/(R1+R2)
