A rock of mass 32kg accidentally breaks loose from the edge, Ask an Expert

Academics

Q. A rock of mass 32 kg accidentally breaks loose from the edge of a cliff and falls straight down. The magnitude of the air resistance that opposes its downward motion is 274 N. What is the magnitude of the acceleration of the rock?

Q. Two point charges q1=2.4 nC and q2=-6.50 nV are 0.1 m apart.

Point A is mid way between them; point B is 8.00x10-2 m from q1 and 6x10-2 m from q2, Take the electric potential to be zero at infinity.
