Answer:
E = 0 r <R₁
Explanation:
If we use Gauss's law
Ф = ∫ E. dA =
/ ε₀
in this case the charge is distributed throughout the spherical shell and as we are asked for the field for a radius smaller than the radius of the spherical shell, therefore, THERE ARE NO CHARGES INSIDE this surface.
Consequently by Gauss's law the electric field is ZERO
E = 0 r <R₁

Answer:
15N
Explanation:
According to Newton's Second Law of Motion
F = m*a
mass = m = 5Kg
acceleration = a = 3m/s^2
=> F = 5kg * 3m/s^2
=> F = 15 N
Answer:
C should be the correct answer,
Explanation:
The gas which produce heat in the atmosphere as it is increased is called a greenhouse gas. Gases like argon , nitrogen, and Oxygen etc. is not a greenhouse gas. Since O3 is not a greenhouse gas it cannot produce heat in the atmosphere .
