Answer:
4000J
Explanation:
Given parameters:
Weight of the man = 800N
Height of ladder = 5m
Unknown:
Gravitational potential energy gained = ?
Solution:
The gravitational potential energy is due to the position of a body.
Gravitational potential energy = weight x height
Now insert the parameters;
Gravitational potential energy = 800 x 5 = 4000J

Two point charges are on the y axis. A 4.50-σC charge (
) is located at y=1.25 cm (
) , and a -2.24-σC charge (
) is located at y=-1.80 cm (
).
The total electric potential at the origin is
.
How to calculate the total electric potential at the origin?
The total electric potential at some point due to several point charges is represented by:

Here,
(Columbic constant)
The total electric potential at point
is the sum of the potentials due to
and
will be:

Substituting the values, we get:

Hence, the total electric potential at the origin is
.4
