well this is the concept used to construct capacitors
if the sphere is conducting
then charges inside the sphere wudnt experience any force due to charges placed outside the sphere

E=h v
3.4 = h v
v= 3.4/h

c =lambda * v

c = 3*10^8
h= 6.626 *10^-34
find it from here

answer plzzzzz some one

hcv-2

capacitors exercise

Q25(d)

someone plzzz

hcv - 2

page 167

Q-25 (b)

is there no one ?????????

plzzz someone answer it

any good book for circuits

i want the theory part for circuit

any good book available

ok sir
then can u plzz answer my first question
let the period of f(x) be T and period of g(x) be T1

now period of f(x) +g(x) will be equal to lcm of T and T1

but what is the period of f(x)/g(x)

how to find it??????????????????

how to find it??????????????????

Q. If the period of sin(nx) / tan(x/n) nbelongs to I

is 6pie

then

find n???????

well sin(nx) period is 2pie/n

tan(x/n) period is pie n

how to proceed from here

the front wheel performs translatory motion
so the friction is backwards

now when we peddal that torque produced is used to rotate the wheel in clockwise
and we know friction opposes motion so its direction is forward this time

cooooool......gr8

if ti is a capacitor , it must be a temporary unstable one
bcos
when both are positively charged
anyone one of the plates can try to attract the negative charge of the othere plates towards it and repel the positive charge away from it

so even if u accept it as an capacitor it must be an unstable one
i think so

and these people are right
dont let go into ur head
just read as hard as u can

give it ur best shot

and the results will turn out to be good

if u are aiming something too high b4 attempting a paper
u may be under a biggg tension

every topper says
" i know i did well in the exam but never expected to get such a good rank "
