Muskan Patra 7 years, 10 months ago

Torque is either force x perpendicular distance Torque=pesin0 here0is angle

Muskan Patra 7 years, 10 months ago

Sorry pe(cos01-cos02)here 0 is angle between dipole moment and field this is workdone

Muskan Patra 7 years, 10 months ago

PE(COSo1-7COSo2)this is work
