JUST PUT THE BRICK ON THE OTHER
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)

Answer:
No
Explanation:
Heat engine is a device which operates between two thermal reservoir.One thermal reservoir supply the thermal energy to the heat engine and another thermal reservoir absorb heat rejected by heat engine.These thermal reservoir are infinite amount of heat capacity system.Temperature of thermal reservoir remain constant always.
So we can say that heat engine can not operate by using only one thermal reservoir.
