Question

(10 pts) A tight guitar string has a frequency of I-kHz as its sixth harmonic. What will be its fundamental frequency if it is played at a length of 45% of its original length? 3. 4. (15 pts) Particles of charge +70yC, +48uC, and -80uC are placed in a line. The center one is 35 cm from each of the others. Calculate the net force on each charge due to the other two. (You should have three answers) 5. (15 pts) Determine the magnitude and direction of the net electric field at point P Assume positive test charge at point P. Each side of the square has length 2m. Charge magnitudes: q,--3 C , q:"-5 C , q,-+2 C ? 2

Explanation / Answer

3) fundamental frequency= 1000/6 Hz

New fundamental frequency= (1000/6)/0.45 = 370 Hz
