Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Electrostatic forces are conservative. This means that mechanical energy (KE +PE) is constant or conserved in absence of
other dissipative forces such as friction.
If a charged particle moves from point A to point B in an electric field (assume that dissipative forces such as friction are
absent), select all the statements that are true.
The symbol A represents the change in the particular quantity. Recall what does positive and negative work mean?
Reflect on what the negative sign represents in each case?
Select multiple answers.
O AKE #-APE
changes in KE and PE are not connected.
O APE=WorkA⇒B
i.e., for positive work, PE increases and for negative work, PE decreases
Ο ΔΚΕ = -ΔΡΕ
i.e., if KE increases, PE decreases and vice-versa
O APE=-WorkÃ→B
i.e., for positive work, PE decreases and for negative work, PE increases
