Waec Model Questions Vol1 2019 Physics Question 2
Practice objective / multiple choice question 2 from the 2019 Waec Model Questions Vol1 Physics examination.
A string of length 0.50 m and linear mass density 0.010 kg m⁻¹ is fixed at both ends. When the string is under an unknown tension T it vibrates in its second harmonic with a frequency of 200 Hz. The tension is then increased by 25 % and the string vibrates in its fundamental with a frequency of 112 Hz (to the nearest whole number). Determine the original tension T in newtons.
