electric field

[void rock]

a 1uC charge is uniformly distributed on a spherical shell given by the equation x(square) + y(square) + z(square) = 25. what will be the intensity of electric field at a point (1,1,2) ?

See from that equation you're given

You can deduce that the distance of a point from origin

Can be represented as the square root of the LHS?

Getting it?

[void rock]

kinda yes kinda no

[tight fable]

See kisi bhi point ki distance kaise likhte hain origin se?

Distance formula?

Coordinate geometry 10th ki?

[void rock]

yaad hai

[tight fable]

Alright

So usme you put x2=x and x1=0

[void rock]

my1 + my2 / (y1 + y2)

i think?

[tight fable]

That's section formula

[void rock]

nhi yaad phir

[tight fable]

And that too incorrect

[void rock]

2 saal purana baat hai

[tight fable]

Hmm understandable ruko

[void rock]

gewgle karne do

[tight fable]

I'll explain

Kar lo

I'll write down too wit

Wait*

[void rock]

aa this onw

ok

hn yaad aya

[tight fable]

Alright

So now you see the question

If we square root both sides in that given equation

Do we get the distance of any point on that sphere?

[void rock]

hn

[tight fable]

'cause for any x,y,z

That relation is always true

[void rock]

damn new pata chala

to is se r ayega

and r se electric feild

okey

[tight fable]

Haan exactly

r se electric field

[void rock]

subah try karungi ab solve

[tight fable]

One thing notice karo

[void rock]

dimag fry ho chuka hai

[tight fable]

Right side me plus minus 5 banega

Minus vala kaise reject karogi?

[void rock]

...uhh

[tight fable]

By saying that the charge is?

Sorry no not that

[void rock]

😭

[tight fable]

Saying the the area vala vector is always?

Outwards

And r is in the direction of that

So you gotta take the positive one

Negative vala means you're going into the origin

Got my point?

[void rock]

hn

guass law bhi aise hai neglect karte hai

[tight fable]

Alright subah try karna

[void rock]

hn

[tight fable]

Hmm

[muted bobcat]

EF will be zero

[muted bobcat]

equation of sphere hai so it will be sperical shell

inside spherical shell EF is zero are no field lines are present

[void rock]

hn ik but merko kaise pta chlega these points are in circle?

[muted bobcat]

which points

[storm ocean]

X²+Y²=k is a circle
Similarly
X²+Y²+Z²=k is a 3d sphere
