Question

A force of 6 kg and another of 8 kg can be applied together to produce the effect of a single force of -
a. 1kg b. 11kg
c. 15kg d. 20kg

Answer 1

(b) 11 kg force

(8-6)=< F(net) =< (8+6)

2 =< F(net) =< 14

Answer 2

Answer:

The single force is 11 kg

(b) is correct option.

Explanation:

Given that,

First force F₁= 6 kg

Second force F₂= 8 kg

We need to calculate the maximum force

$F_{max}=F_{1}+F_{2}$

Put the value into the formula

$F_{max} =6+8$

$F_{max}=14\ kg$

We need to calculate the minimum force

$F_{max}=F_{2}-F_{1}$

Put the value into the formula

$F_{max} =8-6$

$F_{max}=2\ kg$

Range of net force is

$2<F_{net}<14$

The single force is 11 kg because this force lies between maximum and minimum force.

Hence, The single force is 11 kg.
