Question

Two concentric conducting spheres of radii R and 2R are carrying charges Q and _2Q respectively.If the charge on inner sphere is doubled the potential difference between the two spheres will

Answer 1

Hope u know that potential differences (v) of sphere is q/4pi€R
here q=charge ,R=radius
for inner sphere q/4pi€R
for outer sphere -2q/4pi€2R=-q/4pi€R
substrate v inner sphere to outer we get
v differences =2q/4pi€R
now if charge is double of inner sphere then
v=2q/4pi€R
now subt v inner to outer
we get 2q/4pi€R-(-q/4pi€R)=
3q/4pi€R
that is the answer
mark me a brainliest if i got answer

Answer 2

Answer:

Hope u know that potential differences (v) of sphere is q/4pi€R

here q=charge ,R=radius

for inner sphere q/4pi€R

for outer sphere -2q/4pi€2R=-q/4pi€R

substrate v inner sphere to outer we get

v differences =2q/4pi€R

now if charge is double of inner sphere then

v=2q/4pi€R

now subt v inner to outer

we get 2q/4pi€R-(-q/4pi€R)=3q/4pi€Rthat is the answer
