Cross product is a mathematical operatio...

Cross product is a mathematical operation performed between
a)2 vectors
b)2 Scalars
c)One scalar and a vectors
d)None of the option

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
a. If m is palced at mid point of a side then `vecF_(OA)=(4Gm^2)/a^2` in OA direction
`vecF_(OB)=(4Gm^2)/a^2` in OB direction
Since equal and opposite forces cancel each other `vecF_(OC)=(4Gm^2)/({(3)a^2})`
`=(4Gm^2)/(3a^2)` in OC direction
b. If placed at 0 (centroid)
Resultant `vecF_(OA)+vecF_(OB)+vecF_(OC)=0`
(because fore are equal and opposite)
Net gravitatioN/Al force =0
