sir,
in AIEEE ,there was aquwstion regarding electric field and i have some doubt during solving it...plz help me in this question.It goes as...
Let there be a spherically symmetric charge distribution with charge density varying as Rho(r)=Rho -not (5/4 -r/R) & rho(r)=0 for r>R,where r is the distance from the origin.The electric field at a distance r(r
1.rho_not r/3Eo(5/4 -r/R)
2.4pie rho -notr /3Eo (5/4 -r/R)
3.rho-not r/4Eo (5/4 -r/R )
4.4Rho-not r/3Eo (5/4-r/R)
when i attempted it .my ans was wrong,then aftewr it on seeing its solution ,he has taken dq=rho* 4 pie r square but i have doubt it should be dq=rho *4/3 pie r cube.....becoz it is the volume charge density...plz HELP ME
