Question

If the value of atmospheric pressure is 10⁶ dyne cm⁻² in CGS system, find its value in S.I. system.

Answer 1

Answer:

Explanation:

10 N

Answer 2

Answer:

$10^{5} newton/meter^{2}$

Explanation:

Given,

atmospheric pressure=10⁶ dyne cm⁻²

Since, the give quantity is in dyne and cm which is the measurement unit of C.G.S sytem.

We need to convert it in S.I unit.

Since dyne is unit in C.G.S system used to measure force whose equivalent is newton in S.I unit

and 1 dyne=0.00001 newton

also cm is unit in C.G.S system used to measure length whose equivalent is meter in S.I unit

and 1 cm=0.01 m

Now, the given quantity

atmospheric pressure=10⁶ dyne cm⁻²

$= \dfrac{10^6\times0.00001}{1\times0.01\times0.01} \\=10^{5} newton/meter^{2}$
