Question

A uniform electric field of 100 V/m is directed at 30° with the positive x-axis as shown in figure. Find the potential difference V subscript B end subscript minus V subscript A end subscript if OA=2 m and OB=4 m.

  1. 100 left parenthesis 2 minus square root of 3 right parenthesis volt    
  2. 100 left parenthesis 3 minus square root of 2 right parenthesis volt    
  3. negative 100 left parenthesis 3 plus square root of 2 right parenthesis volt    
  4. negative 100 left parenthesis 2 plus square root of 3 right parenthesis volt    

The correct answer is: negative 100 left parenthesis 2 plus square root of 3 right parenthesis volt
