Suppose that a stray neutron with an initial speed of 1.4 x 107 m/s is just barely captured by a nucleus with diameter d = 1.0 X 10-14 m. Assuming the strong force on the neutron isconstant, find the magnitude ofthat force. The neutron's mass is 1.67 X 10-27 kg.

Explanation:

Given data

Initial velocity of neutron v₀=1.4×10⁷m/s

Diameter of nucleus d=1×10⁻¹⁴m

Mass of neutron m=1.67×10⁻²⁷kg

The acceleration of neutron is given from equation :

So its magnitude is a=9.81×10²⁷m/s²

To find magnitude of force we use Newtons second law of motion

So

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
