Answer:
W = 3.21x10⁻¹¹ J
Explanation:
The work required to separate the plates can be calculated using the following equation:
<u>Where</u>:
U₂: is the final stored energy
U₁: is the initial stored energy
C₂: is the final capacitance
C₁: is the initial capacitance
V₁: is the initial potential difference = 5.00 V
V₂: is the final potential difference
The initial and final capacitance is:
<u>Where</u>:
ε₀: is the vacuum permittivity = 8.85x10⁻¹² C²/(N*m²)
d: is the initial distance = 3.00 mm = 3.00x10⁻³ m
A: is the plate area = 865 mm² = 8.65x10⁻⁴ m²
Similarly, C₂ is:
Now, V₂ can be calculated by finding the initial charge (q₁):
Since, q₁ is equal to q₂, V₂ is:
Finally, we can find the work:
Therefore, the work required to separate the plates is 3.21x10⁻¹¹ J.
I hope it helps you!
The student who did the most work is student 2 with 2500 Joules.
<u>Given the following data:</u>
- Force 1 = 500 Newton
- Distance 1 = 1.2 meter
- Force 2 = 500 Newton
- Distance 2 = 5 meter
To determine which of the students did the most work:
Mathematically, the work done by an object is given by the formula;
<u>For </u><u>student 1</u><u>:</u>
Work done = 600 Joules
<u>For </u><u>student 2</u><u>:</u>
Work done = 2500 Joules.
Therefore, the student who did the most work is student 2 with 2500 Joules.
