Question

how to solve this sum?

Answer 1

$\huge\green{ASSALAMUALAIKUM!}$

SOLUTION:-

Charge value for deutron- q1= 1

and mass for deutron- m1 = 2

Charge value for alpha particle- q2 = 2

and mass for alpha particle- m2 = 4

$apply, F=qE$

Force on deutron - F1 = qE
= 1*E
= E

and Force on alpha particle- F2 = qE
= 2*E
= 2E
$apply F = ma$

$a = F / m$

Acceleration for deutron- a1 = F1/m1
a1 =E / 2

Acceleration for alpha particle- a2 = F2/m2
a2 = 2E / 4
a2 = E / 2

$hence, a1 = a2$

$option 3 is the correct answer$
