51:15 homework firstly we will find Va Va =kQ/R - kQ/√2R ; ek ring k karan or ek axis k karan Vb =-kQ/R-kQ/√2R Wext=q∆v = q (vb - va) = q (-KQ/R+KQ/√2R - KQ/R+KQ/√2R) =q (-2KQ/R+2KQ/√2R) take -2KQ/R Common here So q * -2KQ/R ( 1-1/√2) To make it positive multiply whole eq.with -1 Now ans 2KQq/R ( 1/√2 - 1) Hope it helps!

work done in moving a charge +q in from A to B = 2KQq/r (1/1.414 - 1) J
Yup! Work done is -ve
Can u help me by getting this answer I am getting some things wrong
Just provide the solution
@@anuragtiwari02 VA (potential at A ) = KQ/R + ( - KQ/R√2 )
VB (potential at B ) = ( - KQ/R ) + KQ/R√2
workdone in moving charge +q from A to B = ( VB - VA ) * q
workdone in moving charge +q from A to B = ( 2KQ/R√2 - 2KQ/R ) * q
= ( 2KQ/R ( ( 1/ √2 ) -1 ) ) * q

@@sanjanakadam7619 lagta to hai bhai but are you from lakshya neet
51:15 homework firstly we will find Va
Va =kQ/R - kQ/√2R ; ek ring k karan or ek axis k karan
Vb =-kQ/R-kQ/√2R
Wext=q∆v = q (vb - va)
= q (-KQ/R+KQ/√2R - KQ/R+KQ/√2R)
=q (-2KQ/R+2KQ/√2R)
take -2KQ/R Common here
So q * -2KQ/R ( 1-1/√2)
To make it positive multiply whole eq.with -1
Now ans 2KQq/R ( 1/√2 - 1)
Hope it helps!

Work done in moving a charge from point A to B is
(√2KQq/R)(1-√2)
Same mera bhi yahi aya hai 😯🤠🤠
Most genuine ans
Same
Can any of you please share the answer
Literally the best physics teacher of all time
Potential at point A = potential due to ring A at its center + potential due to ring B at point A (axial)
Va=kQ/R-kQ/√2R
Similarly,
Vb=kQ/√2R-kQ/R
Vb-Va=(√2-2)kQ/R
Wdone=q(Vb-Va)
W=(√2-2)kQq/R........................
