As cos component cancel each other, sin components of force add up. We can find the maxima of the equation to find the place of maximum value of force.
2F sinQ = 2 Kq2 sinQ
r2 + d2
4
Put d ( 2F sinQ) = 0
dx
We get
d (2kq2. × X.
dx ( x2 + d2 √ x2. +. d2
4. ( 4)
= 2kq2 +. 2kq2. × (-3 ) x
(x2. +. d2. )3/2. ( x2. d2. )3/2 2
4. 4
On solving we get,
x2 + d2 = 3x2
4
Through this equation,
We get,
X= d
2√2
