Question

an electron(charge=-e) circulates around a helium nucleus(charge=+2e) in an helium atom which particle exerts larger force on other

Answer 1

an electron(charge=-e) circulates around a helium nucleus(charge=+2e) in an helium atom which particle exerts larger force on other.

what didn't you apply Newton's 3rd law of motion ?

according to Newton's 3rd law of motion, “ action and reaction are of equal in magnitude but directed in opposite directions.”

for instance, a particle A exerts a force $F_A$ on another particle B. then particle Particle B also exerts the force, $F_B$ but just opposite in direction. i.e., $\vec{F_A}+\vec{F_B}=0$

here, electrostatic force of attraction acting between electron and helium. now from Newton's law, magnitude of force exerted by electron on helium = magnitude of force exerted by helium on electron.

so, neither of them is large. both particles exerts equal force on each other.

Answer 2

Answer:

both practical exerts equal forcr of each other.
