The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.
<h3>Force on the charge</h3>
The force on the charge is calculated as follows;
F = k(q1q2)/r²
where;
- r is the distance between the charges = 2 m - 1m = 1m
F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²
F = 1.8 x 10⁻⁸ N
Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Answer:
age of rock is 2 million years
Explanation:
Where 
is mass remaining
is original mass
n= t/t(1/2) , which is the ratio of time to half life
= 1000atoms
=250 atoms
t =t(1/2) *n
t(1/2) =1000000 years
t=1000000 *2
t=2,000,000 years
