Question

if F1 andF2are forces acting on alpha particleand electronrespectively in an electric field ,than(a)F1=F2(b)F1>F2(c)F1<F2(d)F1=4F2​

Answer 1

Answer:

F1>F2

As the force experienced by charge 'q' in an electric field 'E'

F = qE

Greater charge experiences greater force in the same electric field.

Since alpha particle is helium nucleus whose charge +2e

while electrons charge is -e

Therefore alpha particle experiences greater force
