Answer:
Explanation:
Let the height of the tree is y and the distance of tree from point B is x.
According to the diagram
x = 0.55 y ..... (1)
(50 + 0.55y) 1.17 = y ..... from equation (1)
58.5 + 0.644 y = y
0.356 y = 58.5
y = 164.3 ft
The potential at a distance r from a charge Q is given by
where ke is the Coulomb's constant.
The charge in our problem is
; for the point at 
, the potential is
For the point at infinity, we immediately see that the potential is zero, because
and so 
.
Therefore, the potential difference between the two points is
where ke is the Coulomb's constant.
