Answer:
Explanation:
We are given that a parallel- plate capacitor is charged to a potential difference V and then disconnected from the voltage source.
1 m =100 cm
Surface area =S=
We have to find the charge Q on the positive plates of the capacitor.
V=Initial voltage between plates
d=Initial distance between plates
Initial Capacitance of capacitor
Capacitance of capacitor after moving plates
Potential difference between plates after moving
Hence, the charge on positive plate of capacitor=
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, kg
Height to which the object is raised above his head, m
Acceleration due to gravity is, m/s²
We know that for a mass raised to a height
, the change in potential energy is given as:
, where,
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
