AIEEE 2003 | Electrostatics Question 276 | Physics

Three charges $$ - {q_1}, + {q_2}$$ and $$ - {q_3}$$ are placed as shown in the figure. The $$x$$-component of the force on $$ - {q_1}$$ is proportional to AIEEE 2003 Physics - Electrostatics Question 274 English

AIEEE 2003 Physics - Electrostatics Question 274 English

$${{{q_2}} \over {{b^2}}} - {{{q_3}} \over {{a^2}}}\cos \theta $$

$${{{q_2}} \over {{b^2}}} + {{{q_3}} \over {{a^2}}}\sin \theta $$

$${{{q_2}} \over {{b^2}}} + {{{q_3}} \over {{a^2}}}\cos \theta $$

$${{{q_2}} \over {{b^2}}} - {{{q_3}} \over {{a^2}}}sin\theta $$

MCQ (Single Correct Answer)

-1

If the electric flux entering and leaving an enclosed surface respectively is $${\phi _1}$$ and $${\phi _2},$$ the electric charge inside the surface will be

$$\left( {{\phi _2} - {\phi _1}} \right){\varepsilon _0}$$

$$\left( {{\phi _2} + {\phi _1}} \right)/{\varepsilon _0}$$

$$\left( {{\phi _1} - {\phi _2}} \right)/{\varepsilon _0}$$

$$\left( {{\phi _1} + {\phi _2}} \right){\varepsilon _0}$$
