Answer:
Step-by-step explanation:
charge q1 is placed at x = 1.90 m and the charge q2 is placed at y = 1.15 m
here, the charge enclosed in a sphere is zero as the radius of sphere is 0.625 m which is less than the x = 1.90 m and y = 1.15 m. So by the Gauss's theorem,
where q is the charge enclosed, as the charge enclosed is zero so the electric flux is zero.
Answer:
There is a 52% probability that she will get it right.
Step-by-step explanation:
We have these following probabilities:
A 40% probability that the student knows the answer to a question.
A 60% probability that the student does not know the answer to a question.
If the student does not know the answer to a question, a 20% probability of getting the question right guessing.
If we choose a question at random from the exam, what is the probability that she will get it right?
40% probability that she knows the answer
60% that she has to guess, when there is a 20% probability of getting it right. So
There is a 52% probability that she will get it right.
