Question

Two positive charges 9nc and 4nc are placed at point A andC respectively of a right angled triangle ABC in which B=90° AB=3cm andBC=2cm find the magnitude and direction of electic feild at point B

Answer 1

it is the required answer

Answer 2

Answer:

the magnitude of electric field 1 is

9 N/c

the magnitude of electric field 2 is

9 N/c

then the resultant electric field will be

9√2 N/c

the direction alpha will be 45°
