The force required to push the box upward is 145.3N and the force to pus the box downward is -109.3N
Data given;
- mass = 15kg
- angle = 30 degree
- acceleration = 1.2 m/s^2
- acceleration due to gravity = 9.8 m/s^2
To move the plane upward, the box will move against gravity.
Let's solve for F
When the force pushes the box down the inclined plane, it moves towards gravity.

Answer:
charge, q = ± 1.1 mC
Given:
Capacitance,
Voltage, V = 110 V
Solution:
The charge on the capacitor plates can be calculated by using the definition of capacitance as :
q ∝ V
where
q = charge
V = potential difference or Voltage
Therefore,
q = CV
Now, charge, q :
q =
Therefore, the charge on the positive plate is:
q = + 1.1 mC
the charge on the negative plate is:
q = - 1.1 mC
