The ratio of the length of a vertical pole and length of its shadow on the horizontal surface is 3 : √3 Assertion(A): The angle of elevation of the sun is 60°. Reason(R): If angle of elevation of the sun is θ, tan θ = 3/√3 = √3 = tan 60°. 1. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true and R is correct reason for A. 4. Both A and R are true and R is incorrect reason for A.
