Question

There are force (10j-j+10k),(4i+3j+2k),(-2i+j+9k) out on a particle and displace it from (5,-3,-7)to(6,2,-2) then find work done

Answer 1

Step-by-step explanation:

S= (i+5j+5k)

W=FS

W=(10i-j+10K)(i+5j+5k)

W=10-5+50

W=55

W=(4i+3j+2k)(i+5j+5k)

W=4+15+10

W=29

W=(-2i+j+9k)(i+5j+5k)

W=-2+5+45

W=48

Answer 2

Answer:

S= (i+5j+5k)

W=FS

W=(10i-j+10K)(i+5j+5k)

W=10-5+50

W=55

W=(4i+3j+2k)(i+5j+5k)

W=4+15+10

W=29

W=(-2i+j+9k)(i+5j+5k)

W=-2+5+45

W=48

If it is wrong report it.........
