a spherical shell of radius R and uniform surface charge density sigma is rotating about its axis with a consant angular velocity omega. find magnetic field at centre

(should taken radius Rsintheta instead of xtantheta)

#

@spring trench help needed

spring trench
#

Just give me 5 mins im on my way to home

fossil flower
#

alr

fossil flower
# fossil flower

well limits 0 se pi hogi but that doesnt make any diff to the ans

spring trench
#

Ans is u sigm r w

#

Ye to nahi?

#

@fossil flower o

fossil flower
#

nope

spring trench
#

Fir kya hai?

fossil flower
#

solve karlo

#

ans bata dia toh youll try to reach that

spring trench
#

Im getting u sigm r w only

fossil flower
#

its less than that

spring trench
#

Uh

#

Let me see kuch glti krdi shyd

fossil flower
#

k

spring trench
#

2/3 it is

#

@fossil flower

fossil flower
#

yep

spring trench
#

Let me see tumne kya gadbad kri hai

#

sin^3 theta aaja cheye

#

Ek extra sin kaha se aagya

fossil flower
#

di se ek sin aaya

#

r^r se sin^2

#

and dx se ek aur

#

@spring trench mila?

dire steppe
#

how tyo integrarte cos^2 theta

fossil flower
#

cos2x = 2cos^2x-1

dire steppe
#

oh

#

bruh

#

oops

#

wu/8 right

#

u is mu naught and w is omega

#

@fossil flower

spring trench
fossil flower
dire steppe
#

ok

spring trench
#

Ye formula konsa lagaya hai tumne?

fossil flower
dire steppe
#

ring

spring trench
#

Mene to biot savart law se kia

dire steppe
#

rings

fossil flower
spring trench
#

Um

#

Ye formula lagane se ig kuch plm aara hai

#

Kuch field ya to Cancle out hora hai jo isse formula me account ni hora

fossil flower
#

har element ki add hogi imo

spring trench
#

Ha shi keh rhe

#

@fossil flower ek bar calculation check kr bhai

fossil flower
#

dude 2 baar karli

spring trench
#

Ek sin theta extra kaha se aara tera

#

Aayega to sin^3 hi

#

Me likh k bheju solution?

fossil flower
#

mein radius Rsintheta aur xtantheta dono leke dekha hai

#

same shit

dire steppe
spring trench
fossil flower
spring trench
#

Ho na ho Kuch calculation error hai

fossil flower
#

dono se same aa rha

spring trench
#

Method thek hai

dire steppe

spring trench
#

Rukja fir me likh k bhejta hu check kr lena kaha tumne gadbad kri

fossil flower
fossil flower
spring trench
#

Oky

#

Sorry di likhna bhul gya di= sigma w R^2 sinQdQ

#

@fossil flower samjhe?

fossil flower
# night zodiac

dx = Rdtheta gives me the correct ans instead of Rsintheta(dtheta)=dx

#

this also removes one sinx

spring trench
#

Ha to yehi galat kia na tumne

fossil flower
#

mera dx is small element in y axis and not along the sphere

#

dx= Rdtheta lena hai

spring trench
#

dx ki value RdQ hi hogi

fossil flower
#

han

spring trench
fossil flower
#

nahi

#

dx is thickness of shell

#

along the sphere

#

but meine differentiate karke y axis mein dx le lia

spring trench
#

Acha acha

#

dx wgera lia hi mt kar

#

theta ke terms me hi likha kr

#

Confusion badhta hai zyada variable banayega to

dire steppe
#

2 pi rcostheta * r dtheta hoga na area

spring trench
#

costheta kyu aayega bhai

#

Sin ayega

#

😭

#

Perpendicular lia na

dire steppe
#

uss ring ka radius will be r cos theta na

#

uske circumference * thickness will give area
