Answer:
1I-4J ,DOT PRODUCT WOULD BE ZERO
Explanation:
WORK DONE =F.S
SO IF THE PARRTICLE MOVES PERPENDICULAR TO THE FIELD WORK DONRE WOULD BE ZERO
ans is y+4x=2
WHAT IS THE VALUE OF GRAVITATIONAL FIELD
4i+j
(4i+1j).(x+y)=0
above will be the equation
no actually it is asking about line where work will b zero
which book question it is?
what I answered is right.
and my explanation is also correct.
