The Total Electromagnetic Power Emitted by the Sun Is $3.8 \times 10 ^ { 26 } \mathrm {~W}$

The total electromagnetic power emitted by the sun is $3.8 \times 10 ^ { 26 } \mathrm {~W}$ . What is the radiation pressure it exerts on the perfectly absorbing surface of a satellite near the orbit of Mercury, which is $5.8 \times 10 ^ { 10 } \mathrm {~m}$ from the sun? The radiation strikes the surface of the satellite perpendicular to the surface. $\left( c = 3.0 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right)$
