Question

the electric potential difference between two points A and B IS 42v . what is the work done by an external agent in caring an charge of 5.0x10-5 from A to B at constant speed?

Answer 1

Answer on Question #47817, Physics, Field Theory the electric potential difference between two points A and B IS 42v . what is the work done by an external agent in caring an charge of $q=5.0\cdot 10^{-5}$ from A to B at constant speed?

Solution

Work is equal to potential energy:

$A=qU=5.0\cdot 10^{-5}\cdot 42=210\cdot 10^{-5}J$
