57. the unit of angular acceleration is
- rad/s2
58. If the length of the cable is doubled, its capacitance C will become
[A]. Doubled [B]. Half
[C]. One-fourth [D]. One-fourth
Answer. A. Doubled
59. What quantity of charge must be delivered by a battery with a Potential Difference of 110 V to
do 660J of Work?
A. 0.6 C B. 6 C
C.60 C D. 600 C
Answer: B. 6C
Explanation: Q = W / V = 660J / 110V = 6C
60. In case of Short Circuit ______Current will flow in the Circuit.
A. Zero B. Very Low
C. Normal D. Infinite
Answer: D. Infinite
Explanation:
At the short circuited point, the voltage difference is very low (about Zero) So then put the value in
I = P/V, so if we put V = 0, Then Current will be infinite.

61. A simply supported beam of span L carries a concentrated load W at its mid-span. The maximum
bending moment M is
- WL/4
62. The unit of moment of inertia of an area is
- mm4
63. which of the following is a vector quantity
A. Linear displacement B. Linear velocity
C. Linear acceleration D. All of these
Answer: Option D
64. The method of measuring distance by pacing is chiefly used in
[A]. reconnaissance surveys [B]. preliminary surveys
[C]. location surveys [D]. all of these
Answer: Option A
65. The height of a water column equivalent to a pressure of 0.15 MPa is
[A]. 15.3 m [B]. 25.3 m
[C]. 35.3 m [D]. 45.3 m
Answer: Option A
Explanation:
p = H*W.
p = 0.15 * 10^6 pa,
w = specific weight of water = 9810 N/m3.
i.e., H = (0.15 * 10^6)/(9810) = 15.3 m.

[A]. direct angle [B]. vertical angle
[C]. horizontal angle [D]. deflection angle
Answer: Option B
70. The horizontal angle between the true meridian and a survey line is called
[A]. magnetic bearing [B]. azimuth
[C]. dip [D]. magnetic declination
Answer: Option B
71. line joining some fixed points on the main survey lines, is called a
[A]. check line [B]. tie line
[C]. base line [D]. none of these
Answer: Option B
72. A line normal to the plumb line at all points is known as
[A]. horizontal line [B]. vertical line
[C]. level line [D]. line of collimation
