An electric field of 210000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -6.2C at this spot?
To find the magnitude of the force acting on a charge at a certain spot, we can use the formula:
Force = Electric Field * Charge
In this case, we are given that the electric field is 210000 N/C and the charge is -6.2C. The negative sign indicates that the charge is negative, which means it is an electron or a negatively charged particle.
To find the magnitude of the force, we substitute the given values into the formula:
Force = 210000 N/C * (-6.2C)
Multiplying the values:
Force = -1,302,000 N⋅C/C
The unit of charge cancels out, leaving us with the force in Newtons:
Force = -1,302,000 N
So, the magnitude of the force acting on a charge of -6.2C at this spot is 1,302,000 N. Since the force is described as "pointing due west," we can also say that the force has a magnitude of 1,302,000 N in the westward direction.
