Required work done, W=QV =(2e)× 25 =50 e=50× 1.6× 10-19 =8× 10-18J

Q. The work done in moving an alpha particle between two points having potential difference $25 V o lt$ is

$8 \times 10^{- 18} J$

$8 \times 10^{- 19} J$

$8 \times 10^{- 20} J$

$8 \times 10^{- 16} J$

$4 \times 10^{- 18} J$

Required work done,
$W = Q V$ $= (2 e) \times 25$
$= 50 e = 50 \times 1.6 \times 10^{- 19}$
$= 8 \times 10^{- 18} J$

Q. The work done in moving an alpha particle between two points having potential difference 25Volt is

8×10−18J

8×10−19J

8×10−20J

8×10−16J

4×10−18J

Required work done, W=QV =(2e)×25 =50e=50×1.6×10−19 =8×10−18J
