An object with charge -4.0μC is placed between a positively charged object to the
elena-s [515]

The net force on the -4.0μC object as a result of this net field will be -10.4 N.

<h3>What is the charge?</h3>

The matter has an electric charge when it is exposed to an electromagnetic field is known as a charge.

The electric field intensity is found as the force per unit charge.

Electric field intensity on the positive charge:

\rm E_1 = \frac{F_1}{Q} \\\\\ \rm   1.2 N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_1 =   - 4.8 \ N

Electric field intensity on the negative charge:

\rm E_2 = \frac{F_2}{Q} \\\\\ \rm   1.4 \ N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_2 =  - 5.6 \ N

The net charge is the algebraic sum of the two charges;

\rm F_{net}=F_1+F_2 \\\\ F_{net}= -4.8 -5.6 \\\\ F_{net}=-10.4 \ N

Hence, as a result of this net field, the net force on the -4.0C object will be -10.4 N.

1. What is the kinetic Energy of a 1500kg object moving at 21 m/s?
Wewaii [24]
The formula for working out kinetic energy is

=122

KE = kinetic energy
m = mass of a body
v = velocity of a body


kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

For the first one I think :
Answer:
KE = 330750 J

I’m not sure about the second one- sorry

The third is
Answer:
KE = 41454 J

Hope it helps and it is correct, sorry if it isn’t !
