Question

If the Universe of size nearly equal to 10 ki power 25 metre were to shrink to the size of earth nearly equal to 10m how large would the earth be on this scale​

Answer 1

The correct data is,

If the Universe of size nearly equal to 10 ki power 25 metre were to shrink to the size of earth nearly equal to 10 power 7 m.

Given:

If the Universe of size nearly equal to 10 ki power 25 metre were to shrink to the size of earth nearly equal to 10 power 7 m.

To find:

How large would the earth be on this scale

Solution:

From given, we have,

The size of the universe = 10^{25} m

The size of the earth = 10^{7} m

We use the formula,

Magnification = Size of earth / Size of universe

= 10^{7} / 10^{25}

= 10^{-18} m.

The actual size of the earth = 10^{7} m

The apparent size of the earth = M × 10^{7} = 10^{-18} × 10^{7} = 10^{-11} m.
