Question

• An electron beam passes through a
region of potential 85V into region of
potential 120V, making an angle of 45 with
direction of electric field. Find the angle
through which beam refracts.
Answer
A.
30.58
B. 36.51
c.
52.41
D. 21​

Answer 1

Explanation:

B:36.51

because 120v-85v=35

so oproximated valueis 36.51
