Six-point masses each of mass are placed at the vertices of a regular hexagon of side l. The force acting on any of the masses is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
From figure,
Similarly, AE = 
AD = AO + ON + ND = l sin 
+ l + l sin 
AB = AF = l
Force on mass m at A due to mass m at B is
Force on mass m at A due to mass m at C is
Force on mass m at A due to mass m at D is
Force on mass m at A due to mass m at E is
Force on mass m at A due to mass m at F is
Resultant force due to 
and 
is
Resultant force due to 
and 
is
Net force on mass m along AD is
