Question

The value of m for which the area included between the curves y² = 4ax and y = mx equals a²/3 is

• A. 1
• B. 2
• C. 3
• D. $\sqrt { 3 }$

Answer 1

Answer: (B)

2

Answer 2

= $\frac { \mathrm { a } ^ { 2 } } { 3 }$

̃ = a²/3

̃ $\frac { 8 a ^ { 2 } } { 3 m ^ { 3 } }$ = $\frac { \mathrm { a } ^ { 2 } } { 3 }$ ̃ m = 2
