Answer:
3rd one
Explanation:
they are pointing right 2 left because most things start at the right in which even if the force of both direction is the same, it acquires more force. i learned this from my science teacher yesterday in Zoom
Answer:
have tried it and the units end up being Nm^-2 (the unit of stress) however the unit for joules is Nm.

Answer:
3.86×10⁶ Newton/coulombs
Explaination:
Applying,
E = F/q....................... Equation 1
Where E = Electric Field, F = Force, q = charge.
From the question,
Given: F = 5.4×10⁻¹ N, q = -1.4×10⁻⁷ coulombs
Substitute these values into equation 1
E = 5.4×10⁻¹/ -1.4×10⁻⁷
E = -3.86×10⁶ Newtons/coulombs
Hence the magnitude of the electric field created by the
negative test charge is 3.86×10⁶ Newton/coulombs
In Oder to determine the density of an object, you must measure
the object's mass and its volume.
With those two numbers in hand, the density may then be calculated,
thusly:
<em>Density = (mass) </em>divided by<em> (volume)</em>.
