Question

Holaa!!!!!
plz answer to above 7th question with explaination.​

Answer 1

Hey there!

Given,

Force (F) = 100 g wt. = 100 * 980 dyne

Mass(m) = 1 kg = 1 * 1000 g

We know,

Reactionary force = mg

                              = 1000 * 980 dyne

Now,

f = μR

where, μ = co-efficient of friction.

μ = f / R

μ = (100 * 980)/ (1000 * 980)

μ = 1 / 10

μ = 0.1

Hope it Helps You!
