Answer 1

The value of theta would be 101°

Explanation:

=> According to the figure,

θ = α + 60

=> If we resolve E into its component, then we get

Ecosα = 2pcos60/4πε₀r³   ...(1)

Esinα = psin60/4πε₀r³        ...(2)

=> If divide eq(2) by eq(1), we get

tanα = 1/2 * tan60

tanα = √3/2

α = tan⁻¹ √3/2

α = 41⁰

=> If we place value of α in above eq of θ, we get

θ = 60 + α

θ = 60 + 41

θ = 101°

Thus, the value of theta would be 101°
