"Suppose some sort of clamp is applied to hold an electron fixed at the distance of 2.5 Angstroms from a lithium nucleus Li3+ which is also clamped into position. Calculate the magnitude of the force between the two fixed particles." The books says the answer is: -2....

Physics
a) Vi= 6.7sin(53) Vi = 5.35 V = Vi - gt at top 0 = Vi - g t so t at top = Vi/g t = .55 y at top = 1 + Vi t - 4.9 t^2 = 1 + 5.35(0.55) - 4.9(.55)^2 y at top = 2.46 b) u = 6.7 cos 53 x = u t x = (6.7 cos 53)(.55) x = 2.22
