Answer 1

A uniform electric field of 100v/m is directed at 30degree with the positive x-axis as shown in the future.find the potential difference vb-va if OA=2m and OB=4m​

Step-by-step explanation:

Electric field in vector form

E = 100 cos30° i + 100 sin 30 j

 

E = 50 sqrt(3) i + 50 j

 

A = ( – 2, 0)

B = (0, 4)

 

∴

 

VBA  =  – integration of (50* sqrt(3) dx + 50 dy)

 

= – 100(2 + sqrt(3))
