An experiment is a type of empirical study that features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables.
What exactly is experimental research?
- A study that carefully follows a scientific research strategy is called experimental research.
- It consists of a hypothesis, a controllable variable, and variables that can be measured, calculated, and compared.
- Most crucially, controlled environments are used to conduct experimental research.
What are the four categories of experimental study?
- While experimentation as a whole encompasses this form of research, individual research designs have certain characteristics.
- The four main design types that are pertinent to user research are correlational, experimental, and quasi-experimental.

Answer:
F = 8.45 * 10^-8 N
Explanation:
The gravitational force is calculated using
F = GMm/r²
Where
G represent gravitational constant = 6.67 * 10^(-11)
M = Mass of the boy = 78kg
m = Mass of the girl = 65kg
r = Distance between them = 2m
Substitute these values in the formula, we have:
F = (6.67 * 10^(-11) * 78 * 65)/2²
F = (6.67 * 78 * 65 * 10^(-11))/4
F = (33816.9 * 10^(-11))/(4)
[Divide by the denominator]
F = 8454.225 *10^(-11)
[Expand]
F = 8.454225 * 10³ * 10^(-11)
F = 8.454225 * 10^(3-11)
F = 8.454225 * 10^-8
[Approximate]
F = 8.45 * 10^-8 N
Hence, the force of attraction between them is 8.45 * 10^-8 N
