Charges,
Explanation:
Given that,
Radius of the balls is 2 mm
The force of repulsion acting on the balls, F = 2.75 N
The separation between the spheres, d = 5.33 cm = 0.0533 m
The force of repulsion between charges is given by :
So, the charge on the spheres is . Hence, this is the required solution.
For the given all options we can find the respective quantity
whenever we have to relate slope of a graph then it is always derivative of quantity on Y axis with respect to X axis
while if we need to find the area of the graph then it is integral of quantity on Y axis with respect to x axis
A. The area under that object's velocity-time graph
this shows area of velocity time graph = = displacement
so its not correct
B. The slope of that object's position-time graph
This shows slope of position time graph = = velocity
so this is correct for velocity
C. The slope of that object's velocity-time graph
This shows slope of velocity time graph = = acceleration
D. The area under that object's position-time graph
this shows the area of position time graph =
this is no physical quantity
So option B is correct
