Answer:
Explanation:
<h3><u>Given data:</u></h3>Frequency = f = 200 Hz
Velocity = v = 400 m/s
<h3><u>Required:</u></h3>Wavelength = λ = ?
<h3><u>Formula:</u></h3>v = fλ
<h3><u>Solution:</u></h3>Put the givens in the formula
400 = (200)λ
Divide 200 to both sides
400/200 = λ
2 m = λ
λ = 2 m
Answer:
25000 V
Explanation:
The formula for potential is
V = Kq/r
Potential at B due to the charge placed at origin O
V1 = K q / OB
V1 = 10000 V
Potential at B due to the charge placed at A
V2 = K q / AB
V2 = 15000 V
Total potential at B
V = V1 + V2 = 10000 + 15000 = 25000 V
