Answer:
The strength of an electric field as created by source charge Q is inversely related to square of the distance from the source. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.

Answer:
option B and C
Explanation:
Control rod are used to regulate the nuclear reactor.
When you insert control rod in the reactor it slows down the nuclear fission inside the reactor and the energy produced in the reactor will be less.
When you remove control road from the reactor the nuclear fission increase inside the reactor and the energy production is high.
Control rod consist of boron, boron absorb the neutron which help to control the nuclear fission.
Hence, the correct answer is option B and C
Answer:
The width is
Explanation:
From the question we are told that
The width of the slit is
The wavelength of the light is
The position of the screen is
Generally angle at which the first minimum of the interference pattern the light occurs is mathematically represented as
Where m which is the order of the interference is 1
substituting values
Now the width of first minimum of the interference pattern is mathematically evaluated as
substituting values
Now the width of the pattern's central maximum is mathematically evaluated as
substituting values
