Question

Find the time required for the electron to move from point A to point B.

a. Kinematic equations
b. Coulomb's law
c. Ohm's law
d. Quantum mechanics

Answer 1

To find the time required for the electron to move from point A to point B, use kinematic equations and solve for time using the equation v = u + at. Hence, option A is correct.

Step-by-step explanation:

The time required for the electron to move from point A to point B can be found using kinematic equations. We can use the equation v = u + at to find the time t. Since the electron is coming to rest, its final velocity v is 0. Assuming the initial velocity u is known, we can rearrange the equation to solve for time t.

• Step 1: Identify the known values. In this case, the final velocity v is 0 and the initial velocity u can be given in the question.
• Step 2: Substitute the values into the equation v = u + at and solve for time t by rearranging the equation.
• Step 3: Calculate the time required for the electron to come to rest.
