The statement about "<span>efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.</span>
Do what?? i know how to do a lot of things to answer but there’s nothing to answer.♀️
The electric potential at point b experienced by the charge cab be determined using the formulas given.
<h3>Electric potential</h3>
The electric potential of a point charge is the work done in moving the charge from infinity to certain point against the electric field.
V = Ed
V = (F/q)d
V = (Fd)/q
where;
- V is the electric potential
- F is electric force
- E is the electric field
- q is the charge
Thus, the electric potential at point b experienced by the charge cab be determined using the formulas given.

Explanation:
It is given that net gravitational force on M is exactly equal to zero. Hence, distance to M from the bigger mass is 3m. Therefore, expression for net force will be as follows.
So,
The first term is negative as the third mass is located between the other two masses. This means that 3 m will be pulling it leftwards (negative x direction) and m will be pulling it rightwards (positive x direction).
On dividing both sides of the equation by G.m.M, we get the following.
0 = 
Using the formula, 
the value of x comes out to be equal to +2.37 (not usabale) and -0.634 (usable).
Hence, we can conclude that the third mass will be located 0.634 meters away from the 3 m mass.
The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.
