(a)
The speed each cell would need when very far away from each other to get close enough to just touch.

Answer to Problem 38QAP
The speed each cell would need when very far away from each other to get close enough to just touch is
Explanation of Solution
Given info:
Mass of each cell is,
Charge on first cell is,
Charge on second cell is,
Diameter of each cell is,
Formula used:
Formula for the electric potential energy for two point charges is,
Calculation:
When the two cells are close enough to just touch, their kinetic energy will be zero. So, they have only electric potential energy at this point.
When the two cells are very far away from each other, their electric potential energy will be zero. So, they have only kinetic energy in this situation.
The kinetic energy of each cell when they are very far away can be calculated as,
The electric potential energy of two cells when they get close enough to just touch can be calculated as,
From the conservation of energy, we get
Substituting the given values in the above equation, we get
Conclusion:
Thus, the speed each cell would need when very far away from each other to get close enough to just touch is
(b)

If the statement is false, correct the statement to make it true. 12. An object in uniform circular motion has a constant velocity while experiencing centripetal acceleration. 13. An object travelling in uniform circular motion experiences an outward centrifugal force that tends to pull the object out of the circular path. 14. An object with less inertia can resist changes in motion more than an object with more inertia. 15. For an object sliding on a horizontal surface with a horizontal applied force, the frictional force will always increase as the applied force increases.arrow_forward
