For each statement about the nuclear force select True or False. In nuclei, it is stronger than the Coulomb force. It acts between a proton and an electron. Its strength goes as 1/distance2, like gravity. It acts between a proton and a neutron. It acts between an electron and a neutron. It acts between two neutrons and also between two protons.

a) True. The Strong interaction is the strong Coulomb force

e) True. It acts between protons, neutrons and between a proton and a neutron

Explanation:

In this exercise you must answer if there are some statements about the nuclei, let's write some of their characteristics

* at the core there is an attractive force called Strong Interaction

* This interaction acts on protons and neutrons alike

* There is a Coulombian-type repulsive force that acts between protons.

Let's review the claims

a) True. The Strong interaction is the strong Coulomb force

b) False. It acts on the elements of the nucleus and here there are no electrons

c) False. It is much greater than gravity and generally described by an exponential

d) False. It acts between components of the nucleus and here there are no electrons

e) True. It acts between protons, neutrons and between a proton and a neutron

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
