A point charge \( Q \) is located on the axis of disc of radius \( R \) at a distance \( b \) from the plane of the disk. If one fourth of the electric flux from the charge passes through the disk, then \( R=\sqrt{\square} b \) (as shown in figure). Fill the space \( \square \).https://bit.ly/YTAI_PWAP https://www.pw.live
