Question

Two equal and opposite forces can produce oscillatory motion?

Sanat K Mukherjee · Accepted Answer

Dear Student,
Two equal and opposite forces cannot produce oscillatory motion In
fact it can't effect the state of the object as the resultant of
their combination is 0 For example, placing a negative charge
between two positive charges and midway between the line joining
the two positive charges Then the negative charge is having an
unstable equilibrium If the negative charge is pushed closer to any
of the positive end charges, it will be pulled towards it
