Answer:
By a positive charge
Explanation:
The electric field is a vector consisting of a magnitude and a direction.
- The magnitude of the field depends on the configuration of the field: for example, for the electric field produced by a single point charge, it is
where k is the Coulomb's constant, q is the magnitude of the charge, r is the distance from the charge.
- The direction of the field corresponds to the force that a positive charge would feel in that field. For example, the electric field produced by a single-point positive charge points away from the charge itself: this is because a positive test charge placed in this field would feel a repulsive force, so it would move away from the source of the field. Vice-versa, the electric field produced by a single-point negative charge points towards the charge itself: this is because a positive test charge placed in this field would feel an attractive force, so it would move towards the source of the field.
Answer:
The new volume is
Explanation:
<h3> This problem is on the application of Boyle's law which states that" the volume of a given mass of gas at constant temperature is inversely proportional to the pressure"</h3>Given data
initial pressure p1= 100atm
initial volume v1= 3.7L
final pressure p2= 32 atm
final volume v2= ?
Apply Boyle's law we have
Substituting our data we have
The new volume is
