A) 6000 N
B) 5000 N
C) 4000 N
D) 3000 N
Correct Answer: A
Solution :
Equation of motion of horse is \[F-f=Ma\] or \[F=Ma+f\] Force of friction \[f={{\mu }_{k}}\,N={{\mu }_{k}}=\,Mg\] So, \[F=Ma+{{\mu }_{k}}\,kg\] \[=M\,(a+{{\mu }_{k}}g)\] \[\therefore \] \[F=(500+1500)\,(1+0.2\times 10)\] \[\Rightarrow \] F = 6000 NYou need to login to perform this action.
