Q10 --> I guess here u dont know why It's D and not C.. ok, As it is an example of projectile motion, u know the horizontal component of velocity is constant so there must be some velocity all the time (at least the horizontal, when there is a horizontal component >0 then obviously there will be a resultant) so velocity is not zero..
Q33--> u know that a helium NUCLEUS has charge of +, double that of a proton BUT it has more mass.. having greater mass of, it will show less deflection, Answer is therefore C.
June 2012 P12 -- > The wire with the small diameter has more Resistance, hence more pd and so particles will flow faster as higher pd. means that more energy is supplied (more energy to push the particles, more speed)
Nov 2012, P11 --> There should be more points on to which the light strikes so it's either B or C, but hence in C the lines are closer, there is more intensity
Nov 2012, P13 --> Check the uploaded file
Nov 2011 P11--> First u have to find the perpendicular distance between the 2 forces.. which is 0.3 sin (50) and u multiply it by 2 (one of the forces) to get 0.4596 rounded to 0.46 which is C..
Please if I am wrong about something correct me
