Answer D It is an enlarged virtual image.
As shown in the figure, any ray parallel to principal axis passes through focus f2 and any ray incident at center of convex lens passes straight. The rays never meet on the other side of the lens but appear to meet on the tree side only. Therefore an enlarged virtual image is formed. A virtual image is formed when ray do not intersect but appear to intersect when produced backwards.
Answer:
Q = 8 μC
Explanation:
The relation between voltage, capacitance and charge can be expressed using the following rule:
Q = C * V
where:
Q is the amount of charge that we want to calculate
C is the capacitance = 4 * 10⁻⁶ F
V is the voltage applied = 2 V
Substitute with the givens in the above equation to get the amount of charge as follows:
Q = C * V
Q= 4 * 10⁻⁶ * 2
Q = 8 * 10⁻⁶ Coulumb
Q = 8 μC
Hope this helps :)
