physics ques.....An electron and a proton with equal momentaenter a magnetic field perpendicular to the field lines.What is the ratio of the radii of curvature of their trajectories..... how duz velocity of chrgd particle affect its 1.mass 2.charge..... write 2 special characteristics of wire of an electric heater..... name 2 materials used for making standard resistance coils .why are these materials preferred over others... find the electric field b/w 2 metal plates 5 mm apart connected by a 12v battery... that's all for now folks ...I will be back soon with more...
Re: physics ques......................Oh cum on guys some one should be able to solve these questions..............
anticipationg a reply......
Re: physics ques.....here are the answers...
1. ratio of radii = 1. basically, in both cases, r = p/(e*B) 2. the rest mass of the particle varies wid velocity as - m' = m/(Root(1-(v^2/c^2))) no idea abt charge.. i think it does not vary... kindly correct me if i am wrong.. 3. wire of an electric heater - - high resistance. - high melting point. 4. constantan and manganin resistivity doesnt vary wid temperature. 5. E = Vd 60 * 10^ (-3) hope tht helped !
Re: physics ques.....Thanx a lot ......
/ / But you got the last one wrong.....the formula is ..E=V/d ...the ans is 2.4 x10^(-3)...... thanx again...
