In a 1-g gravitational field,in 1 s,a light beam will curve beneath a perfectly straight line by
A)much less than 4.9 m.
B)about 4.9 m.
C)much more than 4.9 m.

Question

Quizplus · Accepted Answer

The correct answer is B because the amount of curvature is proportional to the strength of the gravitational field and the time spent in the field. In a 1-g gravitational field, a light beam will curve beneath a perfectly straight line by about 4.9 m in 1 s.
