Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Electric Charges and Coulomb's Law Coulomb’s Law
A particle of charge ‘-q’ and mass ‘m’ moves in a circle of radius ‘r’ around an infinitely long line charge of linear density ‘+λ’. Then time period will be given as:
(Consider k as Coulomb’s constant)
1
\(T^2=\frac{4\pi^2 m}{2k\lambda q}r^3\)
2
\(T= 2\pi r\sqrt{\frac{m}{2k\lambda q}}\)
3
\(T= \frac{1}{2\pi r}\sqrt{\frac{m}{2k\lambda q}}\)
4
\(T= \frac{1}{2\pi}\sqrt{\frac{2k\lambda q}{m}}\)
