Answer:

 m = 1,429 10⁻⁴ kg

Explanation:

For the object to remain floating, the translational equilibrium condition must be met, we set a reference system where the vertical upward direction is positive

          F_e -W = 0

          F_e = W

          q E = m g

we clear

         m = \frac{qE}{g}

let's calculate

        m = \frac{7 \ 10^{-6}  \ 200}{ 7 }

        m = 1,429 10⁻⁴ kg

ANSWER FAST PLEASE HELP
KengaRu [80]

Answer:

B. 175 N

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

Fnet = Fapp + Fg

Where;

Fnet is the net force

Fapp is the applied force

Fg is the force due to gravitation

In this scenario, we observed that both forces are acting in the same direction.

Therefore:

Net force = 100 N + 75 N

Net force = 175 Newton
