Question

Let ABC be a right triangle with right angle at B. Let ACDE be a square drawn
exterior to triangle ABC. If M is the centre of this square, find the measure
of MBC
​

Answer 1

Answer:

Let P be the centre of the square ABCD,

then diagonal of square, = 2 m

so, PA= PB = PC=PD = (1/2) x diagonal = 1 m

Potential at P due to all the charges = 9 x 109 [(q1 / 1) + (q2 / 1) + (q3 / 1) +(q4 / 1) ]

= 9 x 109 [ (2 -3 -4 +5) x 10-6 ]

= 0

Answer 2

Answer:

Step-by-step explanation:

Let P be the centre of the square ABCD,

then diagonal of square, = 2 m

so, PA= PB = PC=PD = (1/2) x diagonal = 1 m

Potential at P due to all the charges = 9 x 109 [(q1 / 1) + (q2 / 1) + (q3 / 1) +(q4 / 1) ]

= 9 x 109 [ (2 -3 -4 +5) x 10-6 ]

= 0
