The $\pi 0$ Meson Has a Mass of 264 Times That of an That

The $\pi 0$ meson has a mass of 264 times that of an electron. What is the approximate range of the force mediated by this particle? ( electron $^ { \text {e } } = 9.11 \times 10 ^ { - 31 } \mathrm {~kg} , c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 }$ J.s)

A) $1.5 \times 10 ^ { - 10 } \mathrm {~m}$
B) $1.5 \times 10 ^ { - 14 } \mathrm {~m}$
C) $1.5 \times 10 ^ { - 12 } \mathrm {~m}$
D) $1.5 \times 10 ^ { - 15 } \mathrm {~m}$
