Question

Name the scientist who invented the spring balance?

(A) Robert Brown

(B) Robert Hooke

(C) Issac Newton

(D) Albert Einstein

Answer 1

Hint Spring balance works on the principle of Hooke’s law. The weight of an object is directly proportional to the elongation of the spring, which is also the statement of Hooke’s law. Spring balances were very famous before the newly came digital balances.


Complete step-by-step answer
Spring balance works on the principle of Hooke’s law, which states that the force applied to a spring is directly proportional to the elongation or contraction of the spring.

The history of the spring balance is quite complicated. Complicated in the sense, it is known that the idea of spring balance came into mind of Robert Hooke first, but the very first spring balance was built by Christiaan Huygens.

Well ,the name of Huygens is not in the options, so our correct answer to the question will be Robert Hooke.

So, the correct answer is option B.

Note In the questions like this, many times we don’t know the answer. But still we can guess the correct answer if you know what is the underlying principle of an object asked in the question, in this case it is spring balance, and the principle is Hooke’s law.
