Answer:
Electric force, 
Explanation:
Given that,
Electric charge 1, 
Electric charge 2, 
Distance, 
To find,
The electric force between these two sets of charges.
Solution,
There exists a force between two electric charges and this force is called electrostatic force. It is equal to the product of electric charged divided by square of distance between them.
k is the electrostatic constant
So, the electric force between these two sets of charges is 
.
Momentum describes an object in motion and is determined by the product of two variables: mass and velocity. Mass -- the weight of an object -- is usually measured in kilograms or grams for momentum problems. Velocity is the measure of distance traveled over time and is normally reported in meters per second. Examining the possible changes in these two variables identifies the different effects momentum can have on an object in motion.
As long as the graph is a straight line they both will give same answer. Edit: In the case of errors,I think the most fitting slope line is more accurate method,because taking average is same as drawing a line from initial to final point of the line and taking its slope.
Hope it helps
Answer:
Radius = 3.96m
Explanation:
In a cyclotron motion, the radius of a charged particle path in a magnetic feild is given by:
r = mv/qB
Where r = radius
m = mass of particle= 9.1×10^-31kg
q = charged electron = 1.6×10^-19C
B = magnetic feid = 7.65×10^6T
V = velocity = 7.65×10^6
r = (9.1×10^-31)×(7.65×10^6) / (1.6×10^-19)(1.10 ×10^-5)
r = (6.9615×10^-24)/(1.76 ×10^-24)
r = 3.96m
