Q2 is impossible for me to show you without being there cos the left hand rule is something you have to see.
Q8 is B cos the mass increases with speed so if the mass is much larger than the mass it has when it is moving, it must be moving at relativistic speed 9close to the speed of light)

Sir there is Question 14 left ... and then I'll disappear into thin air =]
astarmathsandphysics:
14. Between the plates the field E is constant so the force on the charged ball is F=Eq and acceleration is a=F/m=Eq/m also constant (so v is a straight line). When the ball its a plate is is charged with opposite sign so is repelled from plates but as before, acceleration constant so graph os speed against time is straight line for time between the plates.
