Answer:
The force between charges is .
Explanation:
The Coulomb force between the two charges
and
separated by distance
is given by the equation
where is the coulombs constant, and has the value
.
Now in our case
and
,
therefore, the Coulomb force between the charges is
Answer
given,
wavelength = λ = 18.7 cm
= 0.187 m
amplitude , A = 2.34 cm
v = 0.38 m/s
A) angular frequency = ?
angular frequency ,
ω = 2π f
ω = 2π x 2.03
ω = 12.75 rad/s
B) the wave number ,
C)
as the wave is propagating in -x direction, the sign is positive between x and t
y ( x ,t) = A sin(k x - ω t)
y ( x ,t) = 2.34 x sin(33.59 x - 12.75 t)
