a nitrogen nucleus N(A=14,Z=7) bombared with an alpha particle of a certain energy transmutes to an oxygen nucleus(A=17,Z=8) and a proton
a:write a equation for this nuclear reaction
b:find the minimum energy of alpha particle to make this reactin occur
(mass of...

two large horizontal plates are separated by 4mm .the lower plate is at a potential of -6v.what potential should be applied to upper plate to create an electric field strength of 4000 v/m upward in space between the plates
relavant equation:
E=v/d
attempt at question...
which graph correctly relates the electric field strength or electrical potential in field of point charge with distance r from charge.
there are four options,all r straight line graph one is field strength vs r^2,other is field strength vs 1/r and third is potential vs r and fourth is...
a U(a=238,z=92) originally at rest decays spontaneously to form thorium and an alpha particle.no gamma rays is emitted
(a):the alpha particle emitted during decay travels a distance of 25mm in a cloud chamber.given that on average alpha particle creates 4 *raise to power 3 ions per mm of track...
i am in ALEVEL(advanced level)
i know definitions of electric potential,electric field intensity
but please can u tell me why electric field intensity inside charged sphere is zero
2: how the electric potential and electric strength varies with distance and 3:measuring potential difference...
can anyone explain me these terms electric potential,electric field strength inside charged sphere and how they are affected by distance.why electric field intensity is zero inside sphere.what is E-V relation,potential difference and electric field intensity
