Answer:
The magnitude of the force on an electron is 0.069 N.
Explanation:
Given that,
Distance between 1.70 A from the plutonium nucleus, 
The number of electron in iron nucleus is +26e.
To find,
The magnitude of the force between an iron nucleus.
Solution,
Total charge in the plutonium nucleus is, 
. The electric force between charges is given by :
F = 0.069 N
So, the magnitude of the force on an electron is 0.069 N. Hence, this is the required solution.
Scatter light doesn't reflect, reflect light goes off a mirror.
The simplest answer is that gravity is the field created by a mass distribution in the spacetime around it; gravitational force is the force exterted by the field on a test mass in the field.
The answer is light, because a transverse wave is a wave vibrating at right angles to the direction of its propagation
