Calculate the charge on a body of surface area 100 cm2 if it has surface density of charge 5 stat coulomb/ cm2

Dear Student,

surface charge density, σ=5 stat coulomb/cm2surface area, A=100 cm2We know that,σ=qAq=5×100=500 stat coulomb1 stat coulomb=3.335×10-10 C500 stat coulomb=500×3.335×10-10 C500 stat coulomb=1.667×10-7 C

i did this by converting 5statcoulomb/cm2 into coulomb//cm2( approx 1.6)
hence surf. charge = 1.6C/cm2
​GT. A= 100cm2

​hence charge  = (Surf.charge) * Area
= 1.6*100 = 160C

 

WC and thumbs up!

oops, 
the surf. charge denisty will be 1.6 x 10^-9

replace the value of Surf. charge density in the formula and obtain the charge
