Answer:
the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
Explanation:
Given the data in the question;
mass m = 1.30 g = 1.30 × 10⁻³ kg
Charge q = +6.90 µC = 6.90 × 10⁻⁶ C
we know that; g = 9.8 m/s
assuming gravity and the electrostatic force are the only forces exerted on the particle, hence the relation is;
F = mg and F = Eq
so
mg = Eq
make E subject of formula
E = mg / q
so we substitute
E = [ (1.30 × 10⁻³) × 9.8 ] / 6.90 × 10⁻⁶
E = 0.01274 / 6.90 × 10⁻⁶
E = 1846.38 N/C
Since the charge is positive ( + ), { direction is Upward }
Therefore, the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
One light-year is the distance that light travels in vacuum
in one year. It's a unit of distance.
Answer : Kinetic energy is motion of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of position gravitational energy. Applying a force can make some of the electrons move. Electrical charges moving through a wire is called electricity.
hope this helps , have a wonderful day <3
Answer is a.)
Given: Mass m = 70 Kg Height h = 10 m; g = 10 m/s²
Required. Gravitational Potential Energy or P.E
Formula: P.E = mgh
= (70 Kg)(10 m/s²)( 10 m)
P.E = 7,000 Kg.m²/s² or
P.E = 7,000 J
