A uniform electric field of intensity E ...

A uniform electric field of intensity `E = 10^(6) V//m` exist in vertically downwards direction in a region. A particle of mass m = 0.01 kg andcharge `q= 10^(-6) C` is suspended byan inextensible thread oflength `I= 1m`. The particle is displaced slightly from its mean position and released. Calculate the time period ofits oscillation. What minimum velocity should be given to the particle at rest from its equilibrium position so that it completes a full circle in vertical plane? Calculate the maximum and minimum tension in the thread in its circular motion in vertical plane. `[0.6s, 23.42 m//s, 6.59 N,0]`
