A proton, a deutron and an α$$-particle$$ having the same momentum, enters a region of uniform electric field between the parallel plates of a capacitor. The electric field is perpendicular to the initial path of the particles. Then the ratio of deflections suffered by them is

Question

Infinity Learn · Accepted Answer

The deflection suffered by charged particle in an electric field is Since pα $$=$$ pd $$=$$ pp  $$(given)mp$$ : md : mα $$=$$ $$1$$ : $$2$$ : $$4$$ and qp : qd : qα $$=$$ $$1$$ : $$1$$ : $$2$$⇒ yp : yd : yα $$=$$ $$1$$ $$x1$$ : $$1$$ x $$2$$ : $$2$$ x $$4$$ $$=$$ $$1$$ : $$2$$ : $$8$$
