As shown in the diagram, threee equal charges are spaced evenly in a row. The magnitude of each charge is +2e, and the distance

between two adjacent charges is 1.50 nm. Then the central charge is displaced 0.350 nm to the right while the other two charges are held in place. After the displacement, what is the magnitude and direction of the net force that the outer two charges exert on the central charge?

Answer:

4.27*10^(-10) to the left

Explanation:

Force exerted by right charge

F_{right} = \frac{k*(2e)*(2e)}{((1.5 - 0.35)*10^(-9))^2} \\\\F_{right} = \frac{8.99*10^9 * 4 * (1.6*10^(-19))^2}{((1.5 - 0.35)*10^(-9))^2} \\\\F_{right} = 6.96*10^(-10) N

Force exerted by left charge

F_{left} = \frac{k*(2e)*(2e)}{((1.5 + 0.35)*10^(-9))^2} \\\\F_{left} = \frac{8.99*10^9 * 4 * (1.6*10^(-19))^2}{((1.5 + 0.35)*10^(-9))^2} \\\\F_{left} = 2.689*10^(-10) N

Resultant Force

F_{res} =  F_{right} - F_{left}\\F_{res} = 6.96*10^(-10) - 2.689*10^(-10)\\\\F_{res} = 4.271 * 10 ^(-10) N

Hence, right charge exerts more force than left so central experience the above force in left direction.

Answer:

Hi myself Shrushtee.

Explanation:

The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.

What is required to specify the position of an object?(๑•ᴗ•๑)♡​
Mkey [24]

Answer:

Explanation:

To describe the motion of any object, we must be able to describe its position x. It reflects it at any particular time. In other words, we need to specify its position relative to the conventional frame of reference.

Answer:

B transferred.

Explanation:

The kinetic energy is simply transferred by transforming it into other forms of energy.

According to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".

  • The moving baseball posses kinetic energy
  • As it hits the bat, it is converted to mechanical and thermal energy.
  • The bat warms up due to the transfer of the kinetic energy.
  • The mechanical energy of the bat cause work to be done on it and it breaks apart.
  • This ensures that the energy in this process is conserved.
