A)
B)
C)
D)
Correct Answer: D
Solution :
Key Idea: Speed of body at highest point is zero. From equation of motion, we have \[{{Q}^{2}}/(2\pi {{\varepsilon }_{0}}{{a}^{2}})\] when \[2\mu F\] As ball is thrown upwards velocity decreases as height decreases. At the highest point velocity is zero after that body starts downward motion, its speed increases.You need to login to perform this action.
