Answer:
2
Explanation:
#1 is incorrect as there is no upward force that would balance the 5 N downward force
#3 is incorrect 2 is less than 5 = net force downward of 3 N
#4 is incorrect 5 is greater than three = 2 N net force going to the left and 2N going up

Answer:
490 J.
Explanation:
The following data were obtained from the question:
Mass (m) = 5 Kg
Height (h) = 10 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (P.E) =..?
Potential energy is the energy stored in a body by virtue of its location. Mathematically, it can be expressed as:
P.E = mgh
Where:
m is the mass of the object measured in kilograms (Kg).
g is the acceleration due to gravity and the value is 9.8 m/s².
h is the height to which the object is located measured in metre (m)
P.E is the potential energy measured in joule (J).
With the above formula, we can obtain the potential energy possed by the object as follow:
P.E = mgh
P.E = 5 x 9.8 x 10
P.E = 490 J
The,the potential energy possed by the object is 490 J
