Answer: a) 8.2 * 10^-8 N or 82 nN and b) is repulsive
Explanation: To solve this problem we have to use the Coulomb force for two point charged, it is given by:

Replacing the dat we obtain F=82 nN.
The force is repulsive because the points charged have the same sign.
Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .
Resultant force= (2*6^2)^(1/2)
=8.5m/s
answer is B.
Answer:
-7.03645640575 Nm²/C
2.34548546858 Nm²/C
Explanation:
S = Surface area
Electric flux through the base is given by

The electric flux through the base is -7.03645640575 Nm²/C
Inside the tetrahedron there is no charge so total flux will be zero

The electric flux through the sides is 2.34548546858 Nm²/C
