Answer:

Generally, K+ ions ensures re-polarization of  the membrane potential. It always ensures that the neuron returns its resting  state, protecting the  neurons and ensuring episode of rest before the next action potential.

K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.

Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.

Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
