The speed of electrons in a scanning electron microscope is 1 × 107 ms -1. If the proton having the same speed are used instead o. electrons, then the resolving power of scanning proton microscope will be changed by a facto of: (A) 1837 (B) (1/1837) (C) √1837 (D) (1/√1837)

Resolving power propto (1/λ) λ=( h / P )=( h / mv ) So ( RP ) propto ( mv / h ) RP propto P RP propto mv RP propto m

Q. The speed of electrons in a scanning electron microscope is $1 \times 1 0^{7} m s^{- 1}$ . If the proton having the same speed are used instead o. electrons, then the resolving power of scanning proton microscope will be changed by a facto of:

1837

$\frac{1}{1837}$

$1837$

$\frac{1}{1837}$

Resolving power $\propto \frac{1}{λ}$
$λ = \frac{h}{P} = \frac{h}{m v}$
So $(RP) \propto \frac{m v}{h}$
$RP \propto P$
$RP \propto m v$
$RP \propto m$
