Answer:
Answer in explanation.
Explanation:
The relationship between the charge on the capacitor and the potential difference across it is given as follows:
where,
Q = Charge on the Capacitor
C = Capacitance of the Capacitor
V = Potential Difference across the Capacitor
This relationship can be used to find the charge on a capacitor, using the voltmeter, as follows:
<u>The potential difference can be measured through the voltmeter. And the capacitance of the capacitor is a known constant value. Therefore, the charge can be found by taking product of both.</u>
Answer:
f = - 0.143 m = - 14.3 cm
Explanation:
First, we will calculate the power of the combination of lenses:
P = P₁ + P₂
where,
P = Power of Combination = ?
P₁ = Power of first lens = - 5D
P₂ = Power of second lens = - 2D
Therefore,
P = - 5D - 2D
P = - 7D
Now, the focal length can be given as:
<u>f = - 0.143 m = - 14.3 cm</u>
Negative focal length indicates that combination will act as diverging lens.
