The impact on potential energy, if two positively charged small spheres are pushed towards each other.
Answer to Problem 1OQ
Solution:
(c) It increases
Explanation of Solution
Given data:
Given options
- It remains unchanged
- It decreases
- It increases
- There is no potential energy in this solution
Formula used:
The potential energy of two charges (point) separated by distance
From above, it becomes clear that potential energy is inversely proportional to the square of the distance between charges. As distance decreases, potential energy should increase. Hence, the correct option is
Conclusion:
By decreasing the distance between two positive point charges, potential energy is increased.
