Physics · Class 12 · CBSE — Electric Charges and Fields
Two charged particles P and Q, having the same charge but different masses \(\mathrm{m}_{\mathrm{P}}\) and \(\mathrm{m}_{\mathrm{Q}}\) , start from rest and travel equal distances in a uniform electric field \(\vec{E}\) in time \(t_P\) and \(t_Q\) respectively. Neglecting the effect of gravity, the ratio \(\left(\frac{t_P}{t_Q}\right)\) is :
- \(\frac{\mathrm{m}_{\mathrm{P}}}{\mathrm{m}_{\mathrm{Q}}}\)
- \(\frac{\mathrm{m}_{\mathrm{Q}}}{\mathrm{m}_{\mathrm{P}}}\)
- \(\sqrt{\frac{\mathrm{m}_{\mathrm{P}}}{\mathrm{m}_{\mathrm{Q}}}}\)
- \(\sqrt{\frac{\mathrm{m}_{\mathrm{Q}}}{\mathrm{m}_{\mathrm{P}}}}\)
Answer
(D) m _ Q m _ P
