Atoms diameter are on the order of 60 to 600pm (picometers). This is around 6*10^-11.
Answer:
The net Electric field at the mid point is 289.19 N/C
Given:
Q = + 71 nC = 
Q' = + 42 nC = 
Separation distance, d = 1.9 m
Solution:
To find the magnitude of electric field at the mid point,
Electric field at the mid-point due to charge Q is given by:



Now,
Electric field at the mid-point due to charge Q' is given by:



Now,
The net Electric field is given by:


Answer:
258774.9441 m
Explanation:
x = Distance of probe from Earth
y = Distance of probe from Sun
Distance between Earth and Sun = 
G = Gravitational constant
= Mass of Sun = 
= Mass of Earth = 
According to the question


The probe should be 258774.9441 m from Earth
Answer: endurance, strength, balance, flexibility
Explanation:
walking, jogging, swimming, biking
