Integrate the following function
(a) `int_(o)^(2) 2t dt`
(b) `int _(pi//6)^(pi//3) sin x dx`

(c) `int _(4)^(10)(dx)/(x)`
(d) `int _(o)^(pi) cos x dx`
(e) `int _(1) ^(2)(2t -4) dt`

A

`F_(1)=3N, F_(2)=5N, F_(3)=1 N`

B

`F_(1)=3N, F_(2)=5N, F_(3)=6 N`

C

`F_(1)=3N, F_(2)=5N, F_(3)=9 N`

D

`F_(1)=3N, F_(2)=5N, F_(3)=16 N`

Text Solution

Verified by Experts

The correct Answer is:
B
For equilibrium, net resultant for must be zero. These forces form a closed traingle such that
`F_(1)~F_(2) le F_(3)le F_(1)+F_(2)rArr 2N le F_(3) le 8N`
