You'd get an extra 40/60 of the energy, or 2/3. Multiply 5/3 by the required energy to get the actual consumption.
Independent variable
The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.
The electrostatic force is 9 x 10¯³ N.
We need to know about electrostatic force to solve this problem. The electrostatic force is applied on a charge which has near position to another charge. It can be determined by
F = k Q1 . Q2 / r²
where F is electrostatic force, k is Coulomb constant (9 x 10⁹ Nm²/C²), Q1 and Q2 are the charges and r is the radius or distance between the charges.
From the question above, we know that
Q1 = -10 nC = -10 x 10¯⁹ C
Q2 = -10 nC = -10 x 10¯⁹ C
r = 1 cm = 0.01 m
By substituting the following parameters, we can calculate the electrostatic force
F = k Q1 . Q2 / r²
F = (9 x 10⁹ . 10 x 10¯⁹ . 10 x 10¯⁹ / (0.01)²
F = 9 x 10¯³ N
Hence, the electrostatic force is 9 x 10¯³ N.
