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:

Electric field intensity on the negative charge:

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

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

Answer:
In a collision, there is a collision force which endures for some amount of time to cause an impulse. This impulse acts upon the object to change its velocity and thus its momentum
Answer:

since the direction of force is along south so the magnetic field must be upwards
Explanation:
Force on moving charge in magnetic field is given as

here we know this is force on proton
so we have


also we know that the velocity of charge is

now from above formula we have


since the direction of force is along south so the magnetic field must be upwards
Answer:An incandescent light bulb gives only energy of the system in the form of heat. ... The roof of a house is stable but it receives energy from the surroundings and transfers energy through it towards lower temperature side which includes no mass transfer. So, it is best considered as closed system.
