Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which force is responsible for the decay of a proton to a neutron. State the boson.
A
Weak. Z0
B
Weak, W+
C
Strong, g
D
Weak, W-
Explanation: 

Detailed explanation-1: -The W boson changes the makeup of particles. By emitting an electrically charged W boson, the weak force changes the flavor of a quark, which causes a proton to change into a neutron, or vice versa. This is what triggers nuclear fusion and causes stars to burn, according to CERN.

Detailed explanation-2: -Discovered in 1983 by physicists at the Super Proton Synchrotron (SPS) at CERN, the Z boson is a neutral elementary particle. Like its electrically charged cousin, the W boson, the Z boson carries the weak force.

Detailed explanation-3: -The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. So, for example, a neutrino (opens in new tab)that strays close to a neutron can turn the neutron into a proton while the neutrino becomes an electron.
