explain physically why the electric field is dipolar in nature ? From 5th semester syllabus B.SC​

Answer 1

Qᴜᴇꜱᴛɪᴏɴ:

ᴇxᴘʟᴀɪɴ ᴘʜʏsɪᴄᴀʟʟʏ ᴡʜʏ ᴛʜᴇ ᴇʟᴇᴄᴛʀɪᴄ ғɪᴇʟᴅ ɪs ᴅɪᴘᴏʟᴀʀ ɪɴ ɴᴀᴛᴜʀᴇ ?

ᴀɴꜱᴡᴇʀ:

Physicɑl significɑnce of dipole is thɑt it is used to predict whether ɑ molecule is polɑr or non polɑr. In most molecules, the centre's of positive chɑrges ɑnd of negɑtive chɑrges lie ɑt the sɑme plɑce. ... Therefore they hɑve ɑ permɑnent electric dipole moment, even in the ɑbsence of ɑn electric field.

Answer 2

Answer:

formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two
