Answer:

force = 6.53×  10^{-7} N

Explanation:

Given data

downward force = 0.60 m

mass m  = 10^{-7} kg

distance h = 0.40 m

to find out

magnitude of the downward force

solution

we know here mg is apply 0.4 m away from support and

so applied force is d =  0.6 m from support

so

by balancing torque we can calculate force

that is

force = mass  × g ×  h / d

put here all these value

force =  mass  × g ×  h / d

force =  ( 10^{-7}  × 9.81 ×  0.4 )  / 0.6

force = 6.53×  10^{-7} N
