fyt as per the question the magnitude of two like charges are given as q1 and q2.the separation distance is given as r unit.hence the potential energy is given as-
here the potential energy is positive which means the force between two charges is repulsive.the potential energy is maximum which indirectly denotes that the system is unstable.due to this repulsion the smaller charge may accelerate.
coming to the same charges of opposite nature i.e unlike charges-here the magnitude of charges are same and separation distance is also are,so the potential energy will be given as-
here the potential energy is negative .so the system of two charges are attracted by each other.
The answer is b. because they move freely
Answer:
the time required is 0.886 seconds
Explanation:
The computation is shown below:
As we know that the content of the chemical energy that has a calorific value of hydrogen is 141790 kJ /kg
And, the total energy stores is 100,000 kg
Now
E = 141790 × 100,000 kJ
= 14.179 TJ
The time would be
T = E ÷ P
= 14.179 ÷ 16
= 0.886 sec
hence the time required is 0.886 seconds
Answer:
Displacement (i.e. change in its final position)
Explanation:
In classical mechanics work is described as the displacement of the body in the direction of the applied force.
<u>Mathematically given as:</u>
where:
F = force on the body
s = displacement of the body
θ = angle between the force and direction of displacement
While force, acceleration, velocity can also be the answer for the blank space but the displacement effect is visible during and even after the work has been done, so one can notice the change in position of the object even when the person has not seen the process but just the initial condition of the body.
