Answer:
5.648 N/C
Explanation:
Given:
q₁ = 60 pC/m² = 60 × 10⁻¹² C/m²
q₂ = -80 pC/m² = - 80 × 10⁻¹² C/m²
Now,
Electric field is given as:
E =
ε₀ = Permittivity of Free Space
thus, due to charge q₁
E₁ =
or
E₁ = 3.389 N/C
and, due to charge q₂
E₂ =
or
E₂ = 4.519 N/C
Now,
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field = 5.648 N/C
Answer:
Art
Explanation:
Polly's line is linear, while arts line is going up with constant velocity. There for art is going faster.
Momentum is a vector quantity. The direction of the momentum vector is the same as the direction of the velocity of the ball. In a previous unit, it was said that the direction of the velocity vector is the same as the direction that an object is moving.
I hope it's help you..
