I hope this help you!
Answer:
![\vec F_{A} = -67500\,N\cdot (i + j)](https://tex.z-dn.net/?f=%5Cvec%20F_%7BA%7D%20%3D%20-67500%5C%2CN%5Ccdot%20%28i%20%2B%20j%29)
Explanation:
The position of each point are the following:
![A = (0\,m,0\,m,0\,m), B = (0.02\,m,0\,m,0\,m), C = (0\,m,0.02\,m,0\,m)](https://tex.z-dn.net/?f=A%20%3D%20%280%5C%2Cm%2C0%5C%2Cm%2C0%5C%2Cm%29%2C%20B%20%3D%20%280.02%5C%2Cm%2C0%5C%2Cm%2C0%5C%2Cm%29%2C%20C%20%3D%20%280%5C%2Cm%2C0.02%5C%2Cm%2C0%5C%2Cm%29)
Since the three objects report charges with same sign, then, net force has a repulsive nature. The net force experimented by point charge A is:
![\vec F_{A} = \vec F_{AB} + \vec F_{AC}](https://tex.z-dn.net/?f=%5Cvec%20F_%7BA%7D%20%3D%20%5Cvec%20F_%7BAB%7D%20%2B%20%5Cvec%20F_%7BAC%7D)
![\vec F_{A} = -\frac{k\cdot q^{2}}{r_{AB}^{2}}\cdot i - \frac{k\cdot q^{2}}{r_{AC}^{2}}\cdot j](https://tex.z-dn.net/?f=%5Cvec%20F_%7BA%7D%20%3D%20-%5Cfrac%7Bk%5Ccdot%20q%5E%7B2%7D%7D%7Br_%7BAB%7D%5E%7B2%7D%7D%5Ccdot%20i%20-%20%5Cfrac%7Bk%5Ccdot%20q%5E%7B2%7D%7D%7Br_%7BAC%7D%5E%7B2%7D%7D%5Ccdot%20j)
![\vec F_{A} = - \frac{k\cdot q^{2}}{r^{2}} \cdot (i + j)](https://tex.z-dn.net/?f=%5Cvec%20F_%7BA%7D%20%3D%20-%20%5Cfrac%7Bk%5Ccdot%20q%5E%7B2%7D%7D%7Br%5E%7B2%7D%7D%20%5Ccdot%20%28i%20%2B%20j%29)
![\vec F_{A} = -\frac{(9 \times 10^{9}\,\frac{N\cdot m^{2}}{C^{2}} )\cdot (3\times 10^{-9}\,C)}{(0.02\,m)^{2}}\cdot (i + j)](https://tex.z-dn.net/?f=%5Cvec%20F_%7BA%7D%20%3D%20-%5Cfrac%7B%289%20%5Ctimes%2010%5E%7B9%7D%5C%2C%5Cfrac%7BN%5Ccdot%20m%5E%7B2%7D%7D%7BC%5E%7B2%7D%7D%20%29%5Ccdot%20%283%5Ctimes%2010%5E%7B-9%7D%5C%2CC%29%7D%7B%280.02%5C%2Cm%29%5E%7B2%7D%7D%5Ccdot%20%28i%20%2B%20j%29)

Well I mean...we cant see the future. Certain things will be achieveable in different ganerations like going on mars
Answer:
The second classmate is right.
Explanation:
The height of first summit provides the potential energy it will use to climb the following ones.
Ep = m * g * h
Where
m: mass
g: acceleration of gravity
h: height
When the train goes downwards the potential energy is converted into kinetic energy (manifested as speed) and when it climbs it consumes its kinetical energy. As long as no summit is taller than the first the train should have enough energy to climb them.
Also it must be noted that friction also consumes energy, and if the track is too lomg all the energy might be consumed by it.
