Answer:
a) 
b) Efficiency=76.77%
Explanation:
a)
In order to solve this problem, we can use the following formula:
the problem provides us with all the necessary information so we can directly use the formula:
b) In order to find the efficiency, we can use the following formula:
so we get:
Efficiency=76.77%
So the people had to be. This equipment causes space
A.
Kinematics is independent of mass, in most cases.
Answer:
Explanation:
Let v be the velocity acquired by electron in electric field
V q = 1/2 m v²
V is potential difference applied on charge q , m is mass of charge , v is velocity acquired
2400 x 1.6 x 10⁻¹⁹ = .5 x 9.1 x 10⁻³¹ x v²
v² = 844 x 10¹²
v = 29.05 x 10⁶ m /s
Maximum force will be exerted on moving electron when it moves perpendicular to magnetic field .
Maximum force = Bqv , where B is magnetic field , q is charge on electron and v is velocity of electron
= 1.7 x 1.6 x 10⁻¹⁹ x 29.05 x 10⁶
= 79.02 x 10⁻¹³ N .
Minimum force will be zero when electron moves along the direction of magnetic field .
