Question

how much work is done in moving a charge of 3 coulomb from a point at a value 115 to a point at 125 volt

Answer 1

we know that
charge = q = 3 coulombs
potential difference = 125 - 115 =10v
Energy =?
FORMULA: POTENTIAL DIFFERENCE = WORK DONE ÷ CHARGE
V = W ÷ Q
10 = W ÷ 3
W = 3 × 10
W = 30JOULES

Therefore, The work done in moving a charge of 3 coulomb from a point at volts 115 to a point at 125 volts is 30 JOULES

Answer 2

Answer:

Work done moving a charge from one point to another is 30 J.

Explanation:

• When we give a thrust to an obstruction with some energy ‘F’, the body travels with some acceleration or, also, its speed rises or falls susceptible to the movement of the force.
• As the speed surges or downfalls, the kinetic energy of the system changes. We know energy can neither exist assembled nor stand demolished, so the energy must exist converted into some different form.
• In this perspective, it exists termed as work accomplished. The energy reduces when negative energy is completed, and the energy increases when positive work exists completed. Currently, we intention sense how to demarcate work done.

Given,

Charge,$q=3 C$

The Potential at a point, $V_{1}=115 \mathrm{~V}$

The Potential at another point, $V_{2}=125 \mathrm{~V}$

The Potential difference, $\Delta V=V_{2}-V_{1}=10 \mathrm{~V}$

Therefore,

The Work done is given by:

Step 1

$&W=q \Delta V$

$&W=3 C \times 10 V$

$&W=30 J$

Hence, this is the required solution.
