what is the unit of dipole moment?

Text Solution

Verified by Experts

The correct Answer is:
2
In the one dimensional elastic collision with one body at rest, the body moving initially comes to rest & the on which was at rest earlier starts moving the velocity that first body had before collision. So, if `m` & `V_(0)` be the mass & velocity of body,
the change in momentum `= mV_(0) rArr int Fdt = mV_(0) rArr int Fdt = mV_(0) rArr F = (2mV_(0))/(Deltat) = 2 N`
