Answer:
electric potential energy=
so the electric potential energy and distance(r) are inversely proportional.
then, the greatest energy occur in the smallest distance b/n the two balloon.

Answer:
Potential gradient = 1.6 v/m
E.M.F. = potential gradient × balancing length 1.2 = 1.6 × l
l=1.2\1.6
=3\4
3\4=0.75m
convert m into cm 0.75x10
0.75m=75 cm
ans=75 cm

1.97*10⁴N .He cannot survive.
Explanation:
The<em> </em><em>Tidal force</em> can be defined as the difference in force between center of two bodies like center of earth and other bodies.This force stretches the body too and fro from the center of mass of another body due to the difference in the gravitational force.
The tidal force is responsible for various phenomena like ocean tides,celestial body tearing up.
The tidal force is the effect of massive body gravitationally affecting another body.
The tidal force is the difference between the gravitational force of two bodies and directly proportional to the mass of body affecting another body and inversely proportional to the square of radius of the distance between center and the object.
Here let us consider height of person as 2m and d=1m
ΔF= -
=GMm[-
]
=(6.67*10⁻¹¹)(1.99*10³⁰)(1.0)[-
}
ΔF=1.97*10⁴N.
Thus he cannot survive
