Question

One kilogram force equals to
a) 9.8 dyne b) 9.8 x 10^N
c) 98 x 10^ dyne d) 980 dyne​

Answer 1

Answer:

c)9.8×10^4 dyne is the correct answer

Answer 2

Answer:

One-kilogram force equals to 98×10⁴Dyne.i.e.option(c).

Explanation:

The force on a body due to earth is given as,

$F=m\times g$          (1)

Where,

F=force acting on a body

m=mass of the body

g=acceleration due to gravity=9.8m/s²         (constant)

From the question, we have that the mass of the body is one kilogram i.e.1kg

Now equation (1) becomes,

$F=1\times 9.8=9.8N$

We know that,

∴ 1 Newton=10⁵Dyne

$F=9.8N=9.8\times 10^5=98\times 10^4Dyne$

Hence, one-kilogram force equals to 98×10⁴Dyne.i.e.option(c).
