In which situation is maximum work considered to be done by a force
Katena32 [7]

Answer:

  • Work done is maximum when the movement of object is in line and direction of force.  

OR

  • Work done is maximum, when displacement takes place along the direction of force.
  • Work done is given by the equation

                                W = F.S

                            <em>     W  = F. S cos Θ</em>

<em>When cos Θ = 0° ; cos 0 = 1</em>

What is the magnitude of the electric force of attraction between an iron nucleus (q=+26e) and its innermost electron if the dis
iris [78.8K]

Answer:

The magnitude of the force on an electron is 0.069 N.

Explanation:

Given that,

Distance between 1.70 A from the plutonium nucleus, d=1.5\times 10^{-12}\ m

The number of electron in iron nucleus is +26e.

To find,

The magnitude of the force between an iron nucleus.

Solution,

Total charge in the plutonium nucleus is, q=26\times 1.6\times 10^{-19}=4.16\times 10^{-18}\ C. The electric force between charges is given by :

F=\dfrac{kq^2}{d^2}

F=\dfrac{9\times 10^9\times (4.16\times 10^{-18})^2}{(1.5\times 10^{-12})^2}

F = 0.069 N

So, the magnitude of the force on an electron is 0.069 N. Hence, this is the required solution.
