Answer:
correct option is d) 7.0 x 10^-7 N
Step-by-step explanation:
given data
distance = 175 picometers = 1.75 ×
m
to find out
electrical force
solution
we know atomic no of uranium is 92
and charge on electron is = 1.6 ×
C
and electrical force is express as
electrical force =
.............1
put here value we get
electrical force =

electrical force = 6.921 ×
N
so correct option is d) 7.0 x 10^-7 N
