A string fixed at both ends is vibrating in the lowest possible mode of vibration forwhich a point at quarter of its length from one end is a point of maximumdisplacement. The frequency of vibration in this mode is 100 Hz. What will be thefrequency emitted when it vibrates in the next mode such that this point is againa point of maximum?(A) 150 Hz (B) 200 Hz (C) 300 Hz (D) 400 Hz
