The total acceleration of the system is:
$a = \frac{F}{m_A + m_B} = \frac{10}{2 + 3} = 2 \, m/s^2$.
The force exerted by A on B is:
$F_{AB} = m_B \cdot a = 3 \times 2 = 6 \, N$.
A particle of charge \(-q\) and mass \(m\) moves in a circle of radius \(r\) around an infinitely long line charge of linear density \(+\lambda\). Then the time period will be given as:
