The formula for energy of motion is KE = .5 x m x v^2
Ke= Kinetic Energy in Joules
m = Mass in Kilograms
v = Velocity in Meters per Second
Answer:
There will be 2 beta particles released in the decay
Explanation:
See the image below
Explanation:
Below is an attachment containing the solution.
The protons will possess a force pointing to the right.
The force is called Laurentz Force, which is measured by: F = qvB
Here, q is positive for proton, v and B are cross product determined by right hand rule.
To develop this problem we will apply Newton's laws regarding gravitational forces, both in space and on earth. From finding this relationship, leaving the variable of the dust mass open, we will find the relationship of the forces between the two surfaces. Our values are,



Distance between the center of lead sphere to dust particle



Gravitational force of the sphere on the dust particle:



Weight of the dust particle


Ratio of F and W:


Therefore the ratio is
