The magnitude and direction of the force on the charge is -12 N opposite the electric field
To calculate the force on a charge in an electric field, we make use of the formula below.
<u>Formula</u>
F = E×Q .......................... Equation 1
Where:
- F = Force on the charge
- E = Electric Field
- Q = charge
From the question,
Given:
Substitute these values into equation 1
Note: The negative sign indicates that the force is in the direction negative of the electric field.
Hence, The magnitude and direction of the force on the charge is -12 N opposite the electric field

In order to lift the load "L" by "X" meters, the effort "E" needs to travel the distance of 2X meters. (The entire rope needs to be pulled by "E" for a distance of 2X.) Since it is a ratio. it has no units of measurement.
Answer:
A. 9 Watts
B. 2.25 Watts
C. 4.5 Watts
Arranging the circuit from lowest power to highest power we have
Circuit B, circuit C, circuit A.
Explanation:
The power in an electric circuit can be obtained by the following equation:
Power (P) = current (I) x voltage (V)
P = IV
With the above equation, let us calculate the power of each circuit. This is illustrated below:
A. Current (I) = 3A
Voltage (V) = 3V
Power (P) =?
P = IV
P = 3 x 3 = 9watts
B. Current (I) = 1.5A
Voltage (V) = 1.5V
Power (P) =?
P = IV
P = 1.5 x 1.5 = 2.25watts
C. Current (I) = 1.5A
Voltage (V) = 3V
Power (P) =?
P = IV
P = 1.5 x 3 = 4.5watts
Arranging the circuit from lowest power to highest power we have
Circuit B, circuit C, circuit A.
To be honest, there's no sure way to answer that, because you haven't defined your terms and we can't be sure of what j or s might be.
Tell you what I'll do:. I'll assume definitions for j and s, and then I'll answer the question that I invented.
Assume that j stands for Joule, the unit of energy. And assume that s stands for 'second', the unit of time.
Then j/s is the rate of transferring energy or doing work.
Its unit is the Watt, equivalent to 1 Joule per second.
In your system of notation, it would be 'w' .
There is gravity, normal force, and friction. The force of gravity pulls objects towards the center of the earth. The normal force is the surface that exerts On a object. Friction force always acts against the direction of motion.
Hope this helps!
