Figure shown a clamped metal string of length `30 cm` and linear mass density `0.1 kg //m`. Which is taut at a tension of `40N`. A small rider `(` piece of paper `)` is placed on string at point `P` as shown. An external vibrating tuning fork is brought near this string and oscillations of rider are carefully observed. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/RES_PHY_DPP_82_XI_E01_654_Q01.png" width="80%" At which of the following frequencies  the point `P` on string will have maximum oscillation amplitude among all points on string `:`
