Answer 2

The arrangements of charges is given in the picture above.

Given,

Three Charges are +q,+q and -q

distances r,2r, 2r

To Find,

Find a system with zero potential energy.

Solution,

• Zero potential energy refers to the state in which an absolutely inflexible body has no internal energy.
• Perfectly rigid bodies typically experience net energy gains or losses as they enter electromagnetic (if charged) and gravitational (if of mass) forces.
• This is because of the innate characteristics of those fields and how they affect the quantity of the relevant substance in the body.
• Therefore, if the internal energy of the body is precisely zero, a fully rigid body is said to have no potential energy.

Here, U = Zero Potential Energy

so,

$U= \frac{K*q*q}{r} + \frac{k*q*(-q)}{2r} +\frac{k*(-q)*q}{2r}$

$= > U= \frac{kq^{2} }{r} -\frac{kq^{2} }{2r} - \frac{kq^{2} }{2r}$

$= > U = \frac{2kq^{2}- kq^{2} - kq^{2} }{2r}$

$= > U = \frac{2kq^{2} - 2kq^{2} }{2r}$

$= > U = \frac{0}{2r} =0$

Hence, if we are arranging the charges in this way, we can find a system with zero potential energy.
