Question

An important milestone in the evolution of the universe just after the big Bang is the Planck time $t_p$ the value of which depends on three fundamental constants, 'c' speed of light, gravitational constant G and planks constant h. then$t_p\propto .$

• A. $Gh{e}^5$
• B. $\frac{c^5}{Gh}$
• C. $\frac{Gh}{c^5}$
• D. $(\frac{Gh}{c^5}{)}^{\frac{1}{2}}$

Answer 1

The correct option is A $Gh{e}^5$

An important milestone in the evolution of the universe

just after the big Bang is the Planck time tptp the value of

which depends on three fundamental constants, 'c'

speed of light, gravitational constant G and

planks constant h. thentp∝

Hence, Option A is correct.
