Answer: The shortest possible wavelength of sound the organ can produce is 0.224 m
Explanation:
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light =
As wavelength and frequency follows inverse relation, shortest wavelength is produced by highest frequency.
= highest frequency of light =
Thus the shortest possible wavelength of sound the organ can produce is 0.224 m
Answer:
Explanation:
Let the charge on bead A be q nC and the charge on bead B be 28nC - qnC
Force F between them
4.8\times10^{-4} =
=120 x 10⁻⁸ = 9 x q(28 - q ) x 10⁻⁹
133.33 = 28q - q²
q²- 28q +133.33 = 0
It is a quadratic equation , which has two solution
q_A = 21.91 x 10⁻⁹C or q_B = 6.09 x 10⁻⁹ C
