Question

14. Planck's constant (h), speed of light in vacuum (c) and Newton's gravitational constant (G) are taken as three fundamental constants. Which of the following combinations of these has the dimension of length?. ​

Answer 1

Answer:

Speed of light (c)

Explanation:

Speed of light = 3 × 10⁸ m/s

i.e 3 × 10⁸ m/s = 0

=⟩ 1m = (1/3× 10⁸) × s

i.e Distance travelled by light in 1/3× 10⁸ parts of a second is equal to 1m.
