Answer:
B. The algebraic sum of the two electric potentials is determined at a distance r/2 from each of the charges, making sure to include the signs of the charges.
Explanation:
Total electric potential is the sum of all the electric potential. And because electric potential is a scalar quantity you have to account for the signs.
Answer:
no it would not. that is an open circuit and it would need to be closed at the switch for current to flow.
Answer:
Explanation:
Given
mass of cannon and cart is 
Spring constant 
mass of Projectile 
Launch Velocity of cannon 
Launch angle 
As the External Force is zero therefore we can conserve momentum
Initially both Projectile and cannon is at rest
Conserving momentum in horizontal direction
i.e. cannon is moving in opposite direction of Projectile
Answer: I observed that the electric field strength is the same at all points between the plates. The value of the field is 70 volts per meter. This is exactly 100 times the applied voltage. The electric field lines point from the positive plate to the negative plate, as the downward arrow on the detector shows.
Explanation:
the sample answer, don't directly copy it!
