Answer:
a. F = 2.32*10^-18 N
b. The force F is 2.59*10^11 times the weight of the electron
Explanation:
a. In order to calculate the magnitude of the force exerted on the electron you first calculate the acceleration of the electron, by using the following formula:
(1)
v: final speed of the electron = 6.60*10^5 m/s
vo: initial speed of the electron = 4.00*10^5 m/s
a: acceleration of the electron = ?
x: distance traveled by the electron = 5.40cm = 0.054m
you solve the equation (2) for a and replace the values of the parameters:
Next, you use the second Newton law to calculate the force:
m: mass of the electron = 9.11*10^-31kg
The magnitude of the force exerted on the electron is 2.32*10^-18 N
b. The weight of the electron is given by:
The quotient between the weight of the electron and the force F is:
The force F is 2.59*10^11 times the weight of the electron
Answer:
100 J
Explanation:
Given:
Force acting on the crate is,
Displacement of the crate is,
Angle between the direction of force and displacement is,
Now, work done by a force 'F' causing a displacement 'S' such that the angle between the force and displacement is is given as:
Now, plug in 100 N for 'F', 2 m for 'S', and 60° for . This gives,
Therefore, the work done by the force is 100 J.
