Question

The charge on alpha particles is


A
1.6×1010 C
loader
B
3.2×1019 C
loader
C
3.2×1019 C
loader
D
1.6×1019 C
loader

Solution

The correct option is C $$3.2\times10^{-19}$$ C
Alpha particles have a charge of $$+2$$,
Hence, charge on an alpha particle is twice the electronic charge $$ = 2 \times  1.6 \times  10^{-19} C$$
$$q = 3.2 \times  10^{-19} C$$
