SATHEE: Electrostatics Question 350

Electrostatics Question 350

Question: Two point charges $Q$ and ? 3Q are placed at some distance apart. If the electric field at the location of $Q$ is $E$ then at the locality of $- 3 Q$ , it is [BIT 1987]

Options:

A) $- E$

B) $E / 3$

C) $- 3 E$

D) $- E / 3$

Show Answer

Answer:

Correct Answer: B

Solution:

The field produced by charge ? 3Q at A, this is E as mentioned in the Example. $∴$

$E = \frac{3 Q}{x^{2}}$ (along AB directed towards negative charge) Now field at location of ? 3Q i.e. field at B due to charge Q will be $E^{'} = \frac{Q}{x^{2}} = \frac{E}{3}$ (along AB directed away from positive charge)
