Hello Shivani,
Dekho at point P. Idl x r (cap) ko PL vector denote kr rha ha theek ha.
Or diagram me Idl or r cap ke beech ka angle ha 90 degree.
Or components consider krein to yahan ayega dbsin(theta)
Sin90 = 1
Isiliye sirf r square.
I hope smjh aaya hoga.
Agr nhi to feel free to message or comment again.
Keep learning.
