For a 50 kg person receives an absorbed dose of gamma radiation of 20 millirads, the total energy absorbed is mathematically given as
E=0.1457J
<h3>What is the total energy absorbed?</h3>
Generally, the equation for the total energy absorbed is mathematically given as
E=mass*gamma radiation
Therefore
E=50*20*19^{-3}
E=0.1457J
In conclusion, the total energy absorbed
E=0.1457J

The basic definition of pressure is force/area and the scientific community defined that as the Pascal (Pa).
Coulomb's law:
Force = (<span>8.99×10⁹ N m² / C²<span>) · (charge₁) · (charge₂) / distance²
= (</span></span><span>8.99×10⁹ N m² / C²<span>) (1 x 10⁻⁶ C) (1 x 10⁻⁶ C) / (1.0 m)²
= (8.99×10⁹ x 1×10⁻¹² / 1.0) N
= 8.99×10⁻³ N
= 0.00899 N repelling.
Notice that there's a lot of information in the question that you don't need.
It's only there to distract you, confuse you, and see whether you know
what to ignore.
-- '4.0 kg masses'; don't need it.
Mass has no effect on the electric force between them.
-- 'frictionless table'; don't need it.
Friction has no effect on the force between them,
only on how they move in response to the force.

Answer:
The velocity is
.
Explanation:
Given that,
Charge density of the plane 
Distance = 1.05 mm
We need to calculate the electric field due to plane of charge
Using formula of electric field

Put the value into the formula


We need to calculate potential difference
Using formula of potential difference

Put the value into the formula


We need to calculate the work requires to be done to reach the surface of the plane
Using formula of work done

Put the value into the formula


We need to calculate the velocity
Using work energy theorem




Hence, The velocity is
.
