Question

if a box of weighing 6 kg is pulled with an acceleration I'd 0.5 m/s² over a rough surface with a help of a string. if coefficient of friction is 0.1 then the tension i the string is(angle is 30)​

Answer 1

Answer:

2√3 N

Explanation:

Acc.., f= coefficient of friction x N

= ma

so equate the above two:

Tcos30=ma

T=ma/cos30

T= 6x0.5/√3/2

T=2√3N
