Answer:
A) 58 degree
Explanation:
When unpolarized light passing through first polarizer then the intensity of light becomes half as it will get polarized
So let say the intensity of unpolarized light is "Io" then after passing through first polarizer the intensity will become half
Now when this polarized light passing through another polarizer then the intensity of light is given by Malus law
As per Malus law if the angle between two polarizer axis is inclined at some angle
then it is given as




Explanation:
It is given that,
Mass of the object, m = 0.8 g = 0.0008 kg
Electric field, E = 534 N/C
Distance, s = 12 m
Time, t = 1.2 s
We need to find the acceleration of the object. It can be solved as :
m a = q E.......(1)
m = mass of electron
a = acceleration
q = charge on electron
"a" can be calculated using second equation of motion as :




a = 16.67 m/s²
Now put the value of a in equation (1) as :


q = 0.0000249 C
or

Hence, this is the required solution.
Atomic disguise makes helium look like hydrogen. ... A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by two orbiting electrons which carry a negative charge. A hydrogen atom has just one proton and one electron
