Calculate the net force and acceleration of the object. Possible formulas
F=m*a
m = Fla
a = F/m
180 N
40 kg
140 N
Net Force:
N
Acceleration =
m/s

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
