Answer:
1.925 μC
Explanation:
Charge: This can be defined as the product of the capacitance of a capacitor and the voltage. The S.I unit of charge is Coulombs (C)
The formula for the charge stored in a capacitor is given as,
Q = CV ................... Equation 1
Where Q = charge, C = Capacitor, V = Voltage.
Note: 1 μF = 10⁻⁶ F
Given: C = 0.55 μF = 0.55×10⁻⁶ F, V = 3.5 V.
Substitute into equation 1
Q = 0.55×10⁻⁶×3.5
Q = 1.925×10⁻⁶ C.
Q = 1.925 μC
Hence the charge on the plate = 1.925 μC

Answer:
In the analytical method,
- Resolve the vectors into the perpendicular components of the Cartesian coordinates.
- Calculate the magnitude of the resultant vector using the Pythagoras theorem.
Explanation:
- There are two methods to find the magnitude of the resultant vector.
- One is the geometrical method and the other one is the analytical method.
- In the geometrical method, all the vectors are connected the head to tail with the appropriate magnitude and the resultant vector is obtained by joining the initial point and the final point by a vector in the reverse direction. The magnitude of the resultant vector is given by the length of the line.
- In the analytical method, all the vectors are resolved into the perpendicular components.
- Using Pythagoras theorem, the magnitude of the resultant vector can be obtained
- If A and B are the two vectors forming an angle ∅ between them, then the magnitude of the resultant vector is given by the formula

Answer:
False
Explanation:
Vector has a magnitude and direction.
A scalar is just a magnitude or size.
