Chapter 13: Q17P (page 540)

The electric field at a particular location is measured to be <0,-280,0>N/C. What force would a positron experience if placed at this particular location?

Short Answer

Expert verified

The electric force experienced by positron is 0,4.48×10-17,0N.

Step by step solution

01

Identification of given data

The given data can be listed below,

The electric field at a particular point is<0,-280,0>N/C .

02

Concept/Significance of electric force acting on a point

The electric force is a natural force that is similar to gravity in that it is based on the charge of the item rather than its mass, and it may attract or repel objects.

03

Determination of the force experienced by a positron if placed at the particular location

From the definition of electric field, force on the positron is given by,

F=qE

Here, q is the charge on positron and E is the applied electric field.

Substitute values in the above,

role="math" localid="1656913543205" F=1.6×10-19C0,-280,0N/C=0,4.48×10-17,0N

Thus, the electric force experienced by positron is0,4.48×10-17,0N .
