A A particle of mass 2kg is on a rough
horizontal plane. The coefficient of friction
between the plane and the particle is 0.5
Find the least force required to pull the
particle along the plane if it the force is;
a. horizontal
b. at an angle of 30° to the plane

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

it will be a cylinder. with a diameter of 8 and 4 single pieces high
