Answer:
q = 76.8*10⁻⁹ C = 76.8 nC
Explanation:
Assuming no other forces acting on the charges, and that both spheres must be considered as point charges (and as point masses as well) , the force that is responsible for the initial acceleration is the electrostatic force, which obeys Coulomb´s Law.
According to Newton´s 2nd Law, this force is related with the mass and the acceleration as follows:
This same force, expressed as the electrostatic force, is as follows:
As both expressions for F are equal each other, we can solve for q:
⇒ q = 76.8*10⁻⁹ C = 76.8 nC
All of these statements about flux are true, except for the last one - <span>When turning a surface inside of an electric field, the maximum flux is achieved if the electric field vector and the surface vector are perpendicular.
These vectors don't have to be perpendicular, which is why this statement is incorrect, whereas the rest of them are true. </span>
A straight line represents a constant. It means that the speed is changing constantly in equal amounts over equal periods of time.
The amount of energy required to raise the temperature of one gram of water by one celsius degree is called a calorie.
<h3>How can you define calorie?</h3>
In physics, we can define it as a unit of measurement that defines the amount of energy to raise the temperature of 1 gram of water by 1°C. Each material has its unique calorie, however by definition we use water as it is the lowest of all the elements.
Normally, calorimetry is directly linked with the thermal capacity that an element has to contain heat.

Using kinematic equation, v^2 - u^2 = 2as. 5^2 - 3^2 = 2a x 16. a = 0.5m/s^2. So particle will deaccelerate at 0.5m/s^2. ( v = final velocity, u= initial velocity, a= acceleration, s= displacement.)
