Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model,
Speed of the model,
Mass of another model,
Initial speed of another model,
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :
V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
By definition, the electric force is given by:
Where,
q1: electric charge of object number 1.
q2: electric charge of object number 2.
d: distance between both objects
k: proportionality constant
Therefore, the magnitude of the electric force is affected by:
1) The product of the charges of the objects
2) The distance between objects
Answer:
The factors that affect strength of the electric force between two objects are:
1) The product of the charges of the objects
2) The distance between objects
