Answer:
the width of the central bright fringe reduces
Explanation:
In a single-slit diffraction experiment, if the width of the slit through which light passes is increased, then the width of the central bright fringe reduces.
Example, if the width of the slit is doubled, then the width of the central bright fringe will be halved.
Thus, for single-slit diffraction experiment, increase in the width of the slit through which light passes will result in a corresponding decrease in the width of the central bright fringe.

Answer:
Balanced forces
Explanation:
Balanced forces are where two forces of equal size act on an object in opposite directions. It means that in each direction, any pushes and pulls are balanced by another force in the opposite direction.
Answer:
3.6 X 10^17 N; repelling or repulsion
Explanation:
According to coulombs law of electrostatic attraction which states that the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically,
F = kqAqB/d² where;
qA and qB are the charges
d is the distance between the charges.
k is the coulombs constant = 9×10^9Nm²/C²
Given qA = 25C, qB = 40C, d = 0.005m
Substituting the values in the formula we will have;
F = 9×10^9×25×40/0.005²
F = 9×10^12/0.005²
F = 3.6×10^17N
Since the charges are both positive (like charges), they will repel.
According to the law of electrostatic attraction, like charges repel, unlike charges attracts.
