The image is virtual and smaller than the object is a
description of an image that can be produced by a concave lens.
To add, concave lenses<span> are thinner at the middle. Rays of light that pass
through the lens are spread
out (they diverge). It is a type of diverging lens.</span>

Answer:
3.46 x 10^(-13) Joules
Explanation:
The electrical work needed to assemble the system of three charges can be calculated by the following formula:
Where the variables are draw in teh attached image.
In an equilateral triangle:
r_12 = r_13 = r_23 = r
And all the charges are the same, therefore:
q1 = q2 = q3 = q
Replacing these values in the W formula:
Now let's evaluate this formula with
r =2.00 * 10^-15 m
q = 1.6 * 10^-19 C
The dimension of K is M/ T^2
according to the question T=2π square root ofm/k here 2 pi is constant so
T= root of m /k and root of k = root of m/ T now by squaring on both the sides we get the answer k= M/ T^2
complete question :
A spring is hanging down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T=√2πm/k, where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?
