  • Question 3
    4 / -1

    A block weighing 981 N is resting on a horizontal surface. The coefficient of friction between the block and the horizontal surface is μ = 0.2. A vertical cable attached to the block provides partial support as shown. A man can pull horizontally with a force of 100 N. What will be the tension, T (in N) in the cable if the man is just able to move the block to the right?

  • Question 5
    4 / -1

    If y-axis is generator line of the cone ax2 + by2 + cz+ 2fyz + 2gzx + 2hxy = 0, then value of b is equal to:

    Solution

    Since the y-axis is the generator line of the cone, we take its vertices as (0, 1, 0).

    Given,

    Equation of cone = ax2 + by2 + cz2 + 2fyz + 2gzx + 2hxy = 0

    Putting (x, y, z) = (0, 1, 0) in the above equation, we get

    a(0)2 + b(1)2 + c(0)+ 2f(1)(0) + 2g(0)(0) + 2h(0)(1) = 0

    ⇒ b = 0

    Thus, we conclude that if y-axis is generator line of the cone ax+ by2 + cz2 + 2fyz + 2gzx + 2hxy = 0, then value of b is equal to ​0.
