यदि \(^{14}C_r=^{14}C_{r+4}\) है तो (r) का मान क्या है?

If \(^{14}C_r=^{14}C_{r+4}\), what is the value of (r)?

Explanation opens after your attempt
Correct Answer

B. (5)

Step 1

Concept

For equal complementary indices (r+(r+4)=14). In exams form and solve the symmetry equation.

Step 2

Why this answer is correct

The correct answer is B. (5). For equal complementary indices (r+(r+4)=14). In exams form and solve the symmetry equation.

Step 3

Exam Tip

Equal complementary indices के लिए (r+(r+4)=14)। परीक्षा में symmetry equation बनाकर solve करें।
