tht is nt a wheatstone bridge homework cn u apply the star delta thn?

the ans is 20/7 F i think...is tht correct?

sry few days

i did ths que a fewdaysbk n in my que net positive chrge wasnt specified so all the four ans came..

ya didnt see the positive charge ...bt if only positive charges are to be included it will be both...

this can be dne by charge distribution . and applying kirchhoffs loop law.

well after chrge becomes q1-n and q2+n. and force wud become k(q1-n)(q2+n)/r^2. and q1-n=q2+n u cn get value of n in terms of q1 and q2. n frm first eqn u have value of q1xq2...frm tht u will get four values of charges...even if ques demands positive chrge it will be both +10^6 and 3x10^6.

well the ans are 10^-6, -10^-6 ,3 x 10^-6,-3x 10^-6 is tht rite?

1) kx=mg where x=40 cm. 2) time period wud be 2pi(m/k)^1/2 3) equilibrium position wud be wher kx=mg. i.e. 40 cm. n all the other parts cn be solved by using energy conservation.

got the ans .

its already has an extension of 50 cm so it wud be mg(h +x)= kx^2/2
