One of the harmonics of a string fixed at both ends has a frequency of 52.2 Hz and the next higher harmonic has a frequency of 6
Angelina_Jolie [31]

Solution :

Frequency may be defined as the number of observation or number of waves that is taken in per unit time. The unit of frequency is Hertz or Hz.

It is given that :

Successive harmonic frequencies, f = 52.2 Hz

and f' = 60.9 Hz

Therefore, fundamental frequency, F = f' - f

                                                           F = 60.9 - 52.2

                                                          F = 8.7 Hz

Therefore the string which is fixed at both the ends forms all the harmonics.

Determine the total electric potential energy for the charge distribution with three chargers in a straight line
____ [38]

The total electric potential energy is \frac{kq_{1} q_{3} }{r_{13} } + \frac{kq_{2} q_{3} }{r_{23} } + \frac{kq_{1} q_{2} }{r_{12} }.

Electric Potential Energy of a System of Charges :

The system's electric potential energy is equal to the amount of work necessary to create a system of charges by guiding them toward their designated locations from infinity against the electrostatic force without accelerating them. The symbol for it is U.U=W=qV. Electrostatic fields are conservative, therefore the work is independent of the path.

Assume three charges q₁ , q₂ and q₃ bring from infinity to point P.

To bring  q₁ no work is done,

V_{p} = \frac{kq_{1} }{r_{1} }

where, V = electric potential energy.

            q = point charge.

            r = distance between any point around the charge to the point charge.

           k = Coulomb constant; k = 9.0 × 109 N.

Now bring q₂,

V_{2} = \frac{kq_{2} }{r_{2} }

Work done by q₁ ;

W_{1} = V_{p} q_{2}  = \frac{kq_{1}q_{2}  }{r_{12} }

Now bring  q₃,

V_{3} = \frac{kq_{3} }{r_{3} }

Work done on q₃ by q₁ and q₂

W= q_{3} [ V_{1} + V_{2} ]

    =\frac{kq_{1} q_{3} }{r_{13} }+ \frac{kq_{2} q_{3} }{r_{23} }  + \frac{kq_{1}q_{3}  }{r_{12} }

This work done is stored in the form of potential energy.

∴U=W= potential energy of three systems.
