Consider the forces on the pith balls.
The Forces are m*g down and Electrostatic Force horizontally.
Since the string is at theta° and the forces act at right angles
F_electro / F_gravity or E_electro = kq2/r2 = m*g*tantheta°
q = sqrt ( m*g*tantheta° *r^2/k)

Suppose we had a large, positively charged plate in an upright (vertical) position and a point charge with positive charge +Q. In lecture, you saw that a large charged plate gives rise to an electric field which is constant in space: we will call this electric field Eplate. Let us suppose also that we had a s bl with positive charge +q and...

Use the solution you found in
Part 1f to show that the Gompertz model can be rewritten as
dP/dt=−λe^(−rt)P, where λ is a positive constant.
j) Consider grouping the factors in the equation like this:
dP/dt=-(λe^(-rt))P. Make an interpretation of this equation. In
other words, what assumption about tumour growth would lead us to
write down such an equation?
k) Now consider grouping the factors in the equation like this:
dP/dt=−λ(e^(-rt)P). Again, explain what assumption about tumour
