a)	proton and electron	e)	gains same velocity in an electric field for same time
b)	proton and positron	f)	gains same KE in an electric field for same time
c)	Deuteron and α-particle	g)	experience same force in electric field
d)	electron and positron	h)	gains same KE when accelerated by same potential difference.

Proton and electron will gain same KE when accelerated by same potential difference and will experience same force (same charge).

Proton and positron will gain same KE when accelerated by same potential difference and will experience same force (same charge).

Deuteron and α-particle will experience same acceleration( since they have same q/m ratio),So gains same velocity in an electric field for same time.

Electron and positron will gain same KE when accelerated by same potential difference and will experience same force (same charge).
