Question

If i₁ and i₂ are the angles of incidence and emergence respectively and A is the angle of prism, then the angle of deviation is given by

• A. (i₁+i₂)-2A
• B. (i₁+i₂)-A
• C. A (i₁-i₂)
• D. A (i₁+i₂)

Answer 1

The Correct Option is B

The unit of electric charge is the coulomb (C), which is equivalent to the unit ampere-second (A·s). Electric current, on the other hand, is measured in amperes (A), and electric potential is measured in volts (V), while electromotive force is also measured in volts.
Thus, the correct answer is electric charge, as it is the quantity that has the unit ampere-second.

The correct option is (B): (i₁+i₂)-A
