If a vertically upward electric field of strength E=105NC−1 exists in the space, calculate the minimum velocity of the sphere required at the highest point so that it may just complete the circle (g = 10 m/s^2).

A positively charged particle starts at rest 25 cm from a second positively charged particle A radioactive source A small sphere of mass m = 0.5 kg carrying a positive charge q = 110 μC is connected with a light and inextensible string of length of length r=60cm and whirled in a vertical circle. If a vertically upward electric field of strength E=105NC−1 exists in the space flexible it has reached a velocity of 10(2–√)ms−1 . What is the maximum velocity (∈×10ms−1) that the first particle will reach? which is held stationary throughout the experiment. The first particle is released and accelerates directly away from the second particle. When the first particle has moved 25 cm
