angles wrt a normal to mirror
Answer: Newton
Explanation:
Force is measured in Newtons, which are units that equal 1 kg * m/sec2. You can calculate the amount of force that an object experiences with the equation force = mass * acceleration

Answer:
b) in a direction that makes its potential energy decrease.
Explanation:
- As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
- Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite to the change in electric potential energy, which will be always negative, independent of the sign of the charge.
