its the last question
Explanation:
Thats because erosion takes away stuff
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.
M1u1 + m2u2 = m1v1 + m2v2
2 * 3 + 1 * 0 = 2 * 1 + 1 * v2
6 = 2 + v2
v2 = 6 - 2 = 4 m/s.
