On planet Bohrod, the acceleration due to gravity is the sameas that on Earth but there is also a strong downward electric fieldwith the feild being uniform close to the planet's surface. Themagnitude of the uniform electric field is E = 4.75 x10 ^ 5 N/C. A1.00kg mass carrying a charge of 100 microC is connected to avertical spring for which the spring constant is 200N/m. The massis released from rest when the spring is unstretched.
a). By whatmaximum amount does the spring expand?
b). What is the equilibrium position of the mass?
c). How can the velocity be expressed as afunction of time?
