The concept required to solve this problem is quantization of charge.
First the number of electrons will be calculated and then the total mass of the charge.
With these data it will be possible to calculate the percentage of load in the mass.
Here Q is the charge, n is the number of electrons and e is the charge on the electron
Replacing,
According to the quantization of charge the charge is defined as product of the number of electron and the charge on the electron
The total mass of the charge is
Here,
m = Mass of the charge
n = Number of electrons
= Mass of the electron
Replacing we have
Answer:
The correct answer to the question is;
North
Explanation:
Fleming's left hand rule states that the direction of a magnetic field acting on a current carrying conductor is perpendicular to both the force acting on the current carrying conductor and the direction of the current.
Therefore, since the direction of the current is upward and a force is acting with a direction towards the east of the wire then the direction of the magnetic field is northwards.
Answer:
Mechanical advantage = 3
Explanation:
Mechanical advantage, MA = Output force/Input force
Output force = 15 N. Input force = 5 N
MA = Output force/Input force = 15 N/ 5 N = 3
