Answer:
i. F = 1.3 x 
N
ii. The direction of the force of attraction exerted by the proton on the electron is towards the itself (i.e a pull).
Explanation:
Since the given charges are opposite, then the force of attraction is experienced. The force of attraction between the two charges can be determined by:
F = 
where F is the force, k is the constant, 
is the charge of the electron, 
is the charge on the proton, and d is the distance between them.
So that; k = 9.0 x 
N
, = 1.6 x 
C, = 1.6 x
Thus,
F = 
= 
= 1.3061 x
F = 1.3 x N
The force between the charges is 1.3 x N.
ii. The direction of the force of attraction exerted by the proton on the electron is towards the itself.
Answer:
q = 3.356×10^-6C
Explanation:
In a cube of air,the electric field is perpendicular to the top and bottom of the cube,the total reflux = reflux200 + reflux300
But reflux is given by:
Reflux= E×A = E×A cos theta.
Where theta is the angle between the area vector and the electric field.
Total reflux = E300×A cos180 + E200×A cos0
Total reflux = -E300A + E200A
Total reflux =A (E300-E200)
Total reflux is given by Guass's law = Total reflux =q/Eo
q=Eo×total reflux
q= EoA(E200-E300)q= (8.84×10^-12)(100)^2×(100-60)
q=3.356×10^-6C
Answer:
Yes.
Explanation:
-This is because the threshold voltage for the green light is much lower than that of the blue light.
-A longer wavelength in the greenlight necesitates the need for a lower voltage in the banana plug.
