Multiple Choice

To what radius would the sun have to be compressed in order for it to become a black hole? The mass of the sun is $1.99 \times 10 ^ { 30 } \mathrm {~kg} , G = 6.67 \times 10 ^ { - 11 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { kg } ^ { 2 }$ , and $c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s }$

• A) \(6.96 \times 10 ^ { 8 } \mathrm {~m}\)
• B) \(2950 \mathrm {~m}\)
• C) \(3.72 \times 10 ^ { 4 } \mathrm {~m}\)
• D) \(2.66 \times 10 ^ { 6 } \mathrm {~m}\)
• E) \(1470 \mathrm {~m}\)
